Cellular Basis of Life

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material, they have not succeeded in ‘switching it on’ to make it alive, or ‘breathing life’ into it (Rabago et. al,2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate prokaryotic from eukaryotic cells e. Compare plant and animal cells A. The Cell Theory – tructurally made up of 1. What are living things made of? cells. – 2. What can cells do? 3. Where do cells come from? All living things are The cell is the fundamental unit of life. – Cells come from the division of pre-existing cells. B. Cell Structure and Composition CELL MEMBRANE -Serves as the outer boundary of the cell. It is a selective permeable membrane which permits the entrance of substances throughout the cell. CYTOPLASM -Serves as the reservoir of the organelles as it contain all the lifesustaining components. It is a jellylike structure. NUCLEUS -Usually located at the center and nown as the control center of the cell. It regulates and coordinates all the activities of the cell. C. Organelles in the Cytoplasm

They were here first and for illions of years were the only form of life. And even with the evolution of more complex eukaryotic cells, prokaryotes are supremely successful. All bacteria and bacterialike Archaea are prokaryotic organisms. Eukaryotic cells are more complex, evolving from a prokaryote-like predecessor. Most of the living things that we are typically familiar with are composed of eukaryotic cells; animals, plants, fungi and protists. Eukaryotic organisms can either be single-celled or multi-celled.

Large Cell Shape Rectangular Vacuoles A single centrally located vacuole. It takes up almost 90% of the cell volume. The vacuole stores water and maintains turgidity of the cell. Cell Wall Chloroplasts Cell Division A rigid cell wall (made of cellulose) is present around a plant cell that helps it maintain its shape. Present. Chlorophyll is the pigment that traps sun’s energy which is utilized by plants to make food through the process of photosynthesis. This pigment is present in the chloroplasts. Cell division takes place by the formation of cell plate in the center of the dividing cell.

This becomes the cell wall between the two daughter cells. Centrioles Present only in lower forms. Plants instead have microtubule organizing centers (MTOC) that produce the microtubules. Centrosome Absent. Instead two small clear areas called polar caps are present. Absent Lysosomes Golgi Bodies In place of golgi bodies, its sub units known as dictyosomes are present. Animal Cell Smaller than plant cells Circular If any, there are a number of small vacuoles spread throughout the cytoplasm that store water, ions and waste materials. Cell wall is absent. This allows animal cells to adopt different hapes. Absent. As animals lack this pigment, they cannot make their own food. Animal cells divide with the formation of a cleavage furrow. This is formed as the chromosomes move to the ends of the microtubule spindle formed by the centrioles. Present. Centrioles help in division of animal cells by creating microtubule spindles that pull the chromosomes to opposite ends for cell division to occur. Present Present. Lysosomes are vesicles that contain enzymes that destroy dead cell organelles and other cells debis. Complex golgi bodies are present close to the nucleus. E. Articles about Cell

BBC NEWS-Last Updated: Tuesday, 20 November 2007, 16:42 GMT Stem cells are thought to hold huge potential for treating a wide range of disease and disability. Scientists around the world are working on techniques to Refine stem cell therapy. The latest technique, nuclear reprogramming, promises to solve some of the trickiest practical and ethical issues. What are stem cells? Most adult cells in the body have a particular purpose which cannot be changed. For instance, a liver cell is developed to perform specific functions, and cannot be transformed to suddenly take on the role of a heart cell.

Stem cells are different. They are still at an early stage of development, and retain the potential to turn into many different types of cell. Why are they so useful? When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function. Scientists believe it should be possible to harness this ability to turn stem cells into a super “repair kit” for the body. Theoretically, it should be possible to use stem cells to generate healthy tissue to replace that either damaged by trauma, or compromised by disease.

Among the conditions which scientists believe may eventually be treated by stem cell therapy are Parkinson’s disease, Alzheimer’s disease, heart disease, stroke, arthritis, diabetes, burns and spinal cord damage. Stem cells may also provide a useful way to test the effects of experimental drugs. It is also hoped that studying stem cells will provide vital clues about how the tissues of the body develop, and how disease takes hold. Are there different types of stem cell? Yes. Scientists believe the most useful stem cells come from the tissue of embryos.

This is because they are pluripotent – they have the ability to become virtually any type of cell within the body. Stem cells are also found within adult organs. They have not taken on a fina l role, and have the potential to become any of the major specialized cell types within that organ. Their role is to maintain the organ in a healthy state by repairing any damage it suffers. It is thought their potential to become other types of cell is mo re limited than that of embryonic stem cells. But there is evidence that they are still relatively “plastic”. Can they be easily grown in the lab?

Large numbers of embryonic stem cells can be relatively easily grown in culture. However, adult stem cells are rare in mature tissues and science is still working on ways to grow them in the lab in sufficient numbers. This is an important distinction, as large numbers of cells are needed for stem cell replacement therapies. Is the use of stem cells controversial? Very. Campaigners are vehemently opposed to the use of embryonic stem cells. These cells are typically taken from lab-created embryos that are just four or five days old, and are little more than a microscopic ball of cells.

However, opponents argue that all embryos, whether created in the lab or not, have the potential to go on to become a fully-fledged human, and as such it is morally wrong to experiment on them. They strongly advocate the use of stem cells from adult tissue. What is nuclear reprogramming? A new technique, in which cells isolated from skin tissue called fibroblasts are modified by inserting gene-controlling proteins. This chemical cocktail causes the cells to be “reprogrammed” to take on the plastic quality of embryonic stem cells. Why is the nuclear reprogramming an advance?

There are two big potential benefits. The current methods derive stem cells from from existing lab lines, but these cells are foreign to the body, and run the risk of rejection if used to repair or replace damaged or diseased tissue. Nuclear reprogramming can potentially produce a supply of stem cells derived from a patient’s own tissue – avoiding the issue of rejection of the cells. Secondly, the technique does not require the creation of, or destruction of an embr yo, and so is not ethically contentious. Are there safety concerns? Yes.

Some researchers fear that it is possible that stem cell therapy could unwittingly pass viruses and other disease causing agents to people who receive cell transplants. Some research has also raised the possibility that stem cells may turn cancerous. Work also still needs to be done to refine the new technique. Similar results were achieved by two teams using a different combination of gene-controlling proteins. In both cases the success rate in producing new stem cells was also low. Last Updated: Monday, 8 January 2007, 08:58 GMT ‘New stem cell source’ discovered

US scientists say they have discovered a new source of stem cells that could one day repair damaged human organs. Researchers successfully extracted the cells from the fluid that fills the womb in pregnancy and then grew them in lab experiments. The types of stem cell with potentially the most use have so far been derived from specially grown human embryos. But this has created ethical concerns because the embryos are destroyed in the process. Opponents say this is tantamount to cannibalism. Supporters say stem cells offer real hope in treating illnesses like diabetes, Parkinson’s and Alzheimer’s.

Implanted in mice Writing in Nature Biotechnology, the scientists said it should be possible to harness the cells’ ability to grow into different tissue to treat disease. “ It shouldn’t be seen as a race between embryonic stem cells and other sources ” Prof Colin McGuckin Newcastle University However, UK experts had doubts about the feasibility of the technique. They said gathering amniotic fluid from large numbers of women might be difficult. Amniotic fluid contains a large number of cells, many of which come from the developing foetus.

The team from Wake Forest University School of Medicine, in North Carolina, extracted these from fluid samples taken as part of unrelated diagnostic tests during pregnancy, then encouraged them to grow in the laboratory. They found that they had the potential to turn into a wide variety of different cells – the hallmark of potentially useful stem cells. They then transplanted them into mice, and carried out further tests to look at how they performed in a living creature. Again, the results were encouraging, with the stem cells spreading and starting to produce key body chemicals in both brain and liver.

Bone stem cells introduced onto an artificial ‘scaffold’ then implanted into mice also appeared to behave in a similar way to normal bone cells, forming bone even months later. Great interest The conclusion of the researchers was that the amniotic cells were ‘pluripotent’ – capable of becoming many different cell types, and that they held the potential for treatment – particularly on the child from whose mother they were taken, for whom they are an exact tissue match. Dr Paolo De Coppi, now of Great Ormond Street Hospital, who worked on the study, said the amniotic stem cells were similar to, but not identical to, embryonic stem cells.

He said: “Our research suggests that for some clinical applications they may work better than embryonic stem cells. “For example, embryonic stem cells injected into muscle can form teratomas – amniotic stem cells do not do this. “However, the range of applications for these stem cells may be more narrow than for embryonic stem cells. ” Dr De Coppi it might be possible to take amniotic stem cells from a child diagnosed before birth with a problem, and use them to grow new tissue in the laboratory, which would be ready to use to treat the child when it was born.

In theory, it might also be possible to genetically modify a foetus’ own stem cells and inject them back into the amnioitc fluid to correct gene disorders. Possible limitations Professor Colin McGuckin, from Newcastle University, is researching the use of similar cells taken from the umbilical cord at birth. He welcomed the report, saying that it was ‘thorough’ and demonstrated the potential of amniotic stem cells. “The best thing is to have a variety of stem cell sources to provide the best stem cell for patients. Unless researchers do work to demonstrate there are alternatives to embryonic stem cells, the wider public won’t understand that. It shouldn’t be seen as a race between embryonic stem cells and other sources. ” However, he said that harvesting amniotic fluid presented particular difficulties in many cases. “If it is a natural birth, the waters break and they are all over the floor, and you’ve lost them. In this country, the majority of women give birth naturally, which means that fluid could not be collected. “You could conceivably gather amniotic fluid during a caesarean section, but that process could interfere with the experience of giving birth. ” Wednesday, 15 November 2006, 18:00 GMT Stem cells ‘treat muscle disease’

A stem cell breakthrough could lead to a treatment For muscular dystrophy (MD), research has revealed. An Italian-French team found transplanting stem cells into dogs with a version of the disease markedly improved their symptoms. Writing in the journal Nature, the team said the work paved the way for future trials in humans. Scientists said it was a major step forward and bolstered the idea that stem cells could be used to treat MD. “ This is the first piece of research that has convinced me that stem cell therapy could play a role in treatment for Duchenne muscular dystrophy ” Professor Dominic Wells

Muscular dystrophy is a group of genetic disorders that cause the muscles in the body to gradually weaken over time and mobility to be lost. It shortens life p and there is currently no cure. The researchers, led by a team at San Raffaele Scientific Institute, in Milan, Italy, looked at the most common form of the disease, Duchenne muscular dystrophy. This condition, which usually only affects boys, appears in about one in every 3,500 male births and is caused by mutations in a particular gene that lead to a lack of dystrophin, a protein involved in maintaining the integrity of muscle.

The team had previously seen promising results when they injected stem cells into mice with a version of this disease, but turned to dogs for their next trial because they replicate the musclewasting disease more accurately. Mobility returned The researchers used a form of stem cells, gathered from blood vessels, called mesoangioblasts, which are “programmed” to turn into muscle cells. They isolated the stem cells from both healthy dogs and also from MD dogs, with the latter’s stem cells then being modified to “correct” the mutated gene. The scientists proceeded to inject these different types of stem cells into dogs with MD.

They found that transferring the stem cells five times at monthly intervals produced the best results. Overall, injections of stem cells taken from healthy dogs showed the most improvement. Four out of the six dogs who received these stem cells saw the return of dystrophin and regained muscle strength. One dog that was injected at an early-stage of the disease retained the ability to walk, and two dogs injected at a late-stage of the disease had their mobility returned. Of the remaining two, one died early and the other, the scientists believe, did not receive enough cells.

The experiment to inject MD dogs with their own “corrected” stem cells proved less successful, although the dytrophin protein returned. This approach was investigated because, should stem cell treatment move into humans, it would mean patients could be injected with their own cells, minimising the chances of rejection and avoiding the need to take immunosuppressant drugs. The researchers wrote: “The work reported here sets the logical premise for the start of clinical experimentation that may lead to an efficacious therapy for Duchenne muscular dystrophy. ‘Excellent work’ Dr Marita Pohlschmidt, director of research at the Muscular Dystrophy Campaign, UK, said: “We feel encouraged by the work because the results provide initial evidence that we might be one step closer to a stem cell treatment for Duchenne muscular dystrophy. ” Dr Stephen Minger, a stem cell researcher at Kings College London, said: “This is an excellent piece of work demonstrating significant functional improvement in a naturally occurring disease in dogs that is very similar to that in humans. Although it will likely to be some time before this work can move to humans, it is nevertheless an important study in developing therapies for muscular dystrophies. ” Professor Dominic Wells, of the gene targeting group at Imperial College, London, said: “This is yet another example of the vital contribution animal research makes to the development of treatments for human disease. “This is the first piece of research that has convinced me that stem cell therapy could play a role in treatment for Duchenne muscular dystrophy. “

Kay Davies of the MRC Functional Genetics Unit, University of Oxford, said: “The use of stem cells to treat human disease holds great promise, but the actual delivery of such therapy is thought to be many years away. ” The data, she said, changed this view. However, she added that the researchers needed to find out why not all dogs responded positively. Wednesday, 8 November 2006, 16:48 GMT Cell transplants ‘restore sight’ Cell transplants have successfully restored vision to mice which had lost their sight, leading to hopes people could enefit in the same way. UK scientists treated animals which had eye damage similar to that seen in many human eye diseases. They were able to help them see again by transplanting immature retinal stem cells into their eyes. UK experts welcomed the study, published in the magazine Nature, saying it was “stunning” research. “ This is a stunning piece of research that may in the distant future may lead to transplants in humans to relieve blindness ” Professor Andrew Dick University of Bristol

If the results can be translated into a treatment for human eye disease, it could help the millions of people with conditions ranging from age-related macular degeneration to diabetes. Once the cone and rod photoreceptors in a retina are lost, they cannot be replaced. While treatments are being developed which might prevent or delay the loss of these cells, scientists are also seeking to help those already affected. It is thought the retina is one of the best places to try out cell transplant therapy because photoreceptor loss initially leaves the rest of the wiring to the brain intact.

But previous attempts to transplant stem cells, which can turn into any kind of cell in the body, in the hope that they will become photoreceptors have failed because the cells were not developed enough. Harvest In this study, funded by the Medical Research Council, scientists from the University College London Institutes of Ophthalmology and Child Health and Moorfields Eye Hospital transplanted cells which were more advanced, and already programmed to develop into photoreceptors. ? 1 – Early stage retinal cells are taken from a newborn mouse ? 2 – They are transplanted into the retina of a mouse which has lost its sight ? – The cells implant and connect with existing cells in the eye, restoring some sight to the mouse. The team took cells from three to five-day-old mice, a stage when the retina is about to be formed. The cells were then transplanted into animals which had been genetically designed to have conditions which meant they would gradually lose their sight – either mimicking the human disease retinitis pigmentosa or age-related macular degeneration. The transplants were successful; the photoreceptors implanted and made electrical connections to the animals’ existing retinal nerve cells – key to allowing them to see again.

Tests showed that the mice’s pupils responded to light and that there was activity in the optical nerve, showing signals were being sent to the brain. Dr Jane Sowden, one of the study’s leaders, said: “Remarkably, we found that the mature retina, previously believed to have no capacity for repair, is in fact able to support the development of n ew functional photoreceptors. ” ‘Not false hope’ To get human retinal cells at the same stage of development, however, would involve taking stem cells from a foetus during the second trimester of pregnancy.

But Dr Robert MacLaren, a specialist at Moorfields Eye Hospital who worked on the research, said they did not want to go down that route. He said the aim now would be to look at adult stem cells to see if they could be genetically altered to behave like the mouse retinal cells. There are some cells on the margin of adult retinas that have been identified as having stem cell -like properties, which the team says could be suitable. Dr MacLaren stressed it would be some time before patients could benefit from such a treatment, but he said that at least it was now a possibility. Every day, I sit in my clinic and have to tell patients that there’s nothing I can do. “I don’t want to give patients false hope. But at least now, if I see a young patient, I can say that there might be something within your lifetime. ” Dr Stephen Minger, a stem cell expert at King’s College London, said: “I think this is important, superb research – it clearly shows that the host environment is important in directing the integration of transplanted cells. ” But Andrew Dick, professor of ophthalmology at the University of Bristol, added: “As with any basic research we have to be careful not to overhype.

Remove the Jello from the plastic cup onto the paper plate. We had some problem with this. The students may need to run the knife around the very outside edge of the Jello to loosen it. There are some suggestions that you might spray the cup with Pam or some other non -stick material. We did not get a chance to try this yet. Running warm water over the cup may also loosen the Jello. 3. Cut the Jello/Knox in half and remove the top half. Turn over the top and set it on the plate beside the bottom half 4. Use the spoon to dig out a hole in the bottom half of the Jello/Knox cytoplasm . Just pushing the food pieces into the Jello causes it to crack and come apart, making for a very messy cell.

Place the gumball in this hole to represent the nucleus of the cell. 5. Using the spoon to make spaces and your diagram as a guide, place the other cell parts into the cell. Parts can be put into both the top and bottom half of the Jello/Knox cell 6. Take the top part of the cell and carefully place it on the top. If the cell feels soft, you can put the parts back into the plastic cup, then turn it over onto the paper plate. Then carefully remove the plastic cup. 7. After reviewing the parts one final time, those students who wish to can feast on their cell. Please use clean spoons in case the spoon you were working with fell on the floor or the table. It’s Alive, Alive.

Conservative vs. Liberal

Conservative vs. Liberal Dimitri Khago PSY/201 Sunday, August 05, 2012 Mariah Degruy Conservatives vs. Liberals Not just as Americans but as human beings we all want the same basic things in our daily lives. We all seek freedom and yearn for prosperity. We all seek for what is fair in life and not just our lives separately, but the lives of our nation’s people. We want less people to suffer as much as possible, especially our children. We all seek the best for our health being. We all want a crime free nation and crime free streets in our communities.

We all want a freedom to speak and voice our opinions; yet the one major key argument is how do we achieve all of these? With all that has been going on in our nation’s economy, we begin to analyze one of the very most important, yet controversial political issue that we are facing: Liberal or Conservative? Although we are united as a whole nation, but when concerning our nation’s political policies we are very much divided. Each of us has our own beliefs and our own opinion, but the beauty of this is that this is what makes this country.

This belief was instilled in our bloods from the day this great nation was formed, by our political forefathers up until now. We sometimes call these beliefs Left or Right based on the political spectrum. The political spectrum We have learned to become conservative toward the nation, our nation’s people and our nation’s policies, as well as we have learned to become liberal toward the nation, our people and our nation’s policies. Which is right you might ask, that all depends on every individuals different view and opinion to do what is right and best for them?

Conservatives and Liberals differ on what they believe is correct for the government. They seek different essential needs, different government program support, different social views, and very different economic views. As humans we all seek the same basic needs to live. These needs are Life, Liberty, and Pursuit of happiness a well-known phrase from the United States Declaration of Independence. We all have the right to lead our own life in which we so choose. We all have the right to have our belief and make our own decisions and stand to our own judgments.

The most important matter is that we have the right to do whatever it takes to make ourselves feel happy without harming anyone one stepping over the boundaries of others. In order to protect our individual human rights the bill of rights were established. These laws which allow the people the ability to live by these deserved rights as a human being are what distinguish us from a free person and one who is not free. If one is convicted of a felony these particular laws spoken of are no longer valid to them – the right to vote, the right to serve on a jury, and the right to bear arms are all void.

Although some states are adjusting these laws to their own liking, you as a criminal are no longer privileged to take part in these opportunities because of the crime committed, they are therefore taken away from you “…Other states may permanently ban felons from voting even after being released from prison, parole, and probation, and having paid all their fines. ”(State Felon Voting Laws). There are many programs in which our government runs, and many of these programs are the split between the conservative or the liberal side.

Liberals seem to view their government better as a larger government and support those programs which make this a reality. These include many programs, but one in particular is welfare. In the eyes of a liberal, this program is looked very highly upon. It helps those in need the ability to stand on their feet and not be out on the street. Although ideally this is a great help, but nowadays in our country, many people seem to take advantage of this opportunity and cheating the rest of society who need this help.

With the educational program, a liberal supports not only public schools and a higher teacher salary, but also smaller classroom for the students. They support the idea that the classrooms should not be thirty-plus children, but also smaller more controlled environment” Vouchers take money away from public schools. ” (Conservative vs. Liberal Beliefs. ). Now if you were to ask a conservative about education, they believe in the art of competition “School vouchers create competition and therefore encourage schools to improve performance. (Conservative vs. Liberal Beliefs. ). Schools should be all private so that they compete with lower costs and the parents have the opportunity to decide where they want their child to attend, and what kind of education they want for their child. Another program a conservative strongly believes in is canceling all the failed social support programs. Why should a country hold on to a program that is not helping anyone that is in need of the assistance, but financially supporting those well off, and are working and supporting their own families.

Although being in the twenty-first century has expanded our view upon socialistic views, conservatives feel that we should not change our ruling on marriage and that it must stay traditional between a man and a woman. Since America was founded on grounds of religious freedom, and the Bible was and is our most highly looked upon views, conservatives feel that we shall stick to these traditional views and not support the idea of abortion or embryonic stem cell research.

One must not abort a child, since that is the same as murder “Abortion is the murder of a human being. ” (Conservative vs. Liberal Beliefs. ). One must also not participate in stem cell research since that too is destroying a life. This is where the argument comes in on the Liberal side. Liberals believe it is not up to us to decide if marriage shall stay between a man and a woman, what is so wrong with a man and man marrying or a woman and woman?

Since this country was found on the principles of freedom and the rights to make our own decisions, the personal lives of Americans shall not be dictated by the government because of what they think is right. It has not yet been proven that a fetus inside a woman is a child or a fetus. The argument remains that a child is only a child when it takes its first breath, or that a child is a child when it is conceived. Shouldn’t the mother decide if she wants to give birth to this fetus?

She will be bearing all the pain, so it should be her right to decide “A woman has the right to decide what happens with her body. A fetus is not a human life, so it does not have separate individual rights. ” (Conservative vs. Liberal Beliefs. ). Now if you can save a life wouldn’t you? If you aren’t hurting anyone or anything with embryonic stem cell research, then scientist should be able to harvest these stem cells to help a life “…Stem cells derived from embryos in the very earliest stages of development; these cells have long been thought by scientists to have an xtraordinary potential for alleviating the suffering caused by conditions ranging from diabetes to Alzheimer’s disease to spinal cord injury. ” (Gold). Money is what runs the country, one thing these two political stances have in common are the want and need for more jobs. A conservative wants the federal government not to tax the rich as high and should spend so much less. These big businesses should get the tax breaks they want and deserve to increase and generate their revenue, so that they can stimulate and keep the economy stable and grow to be much stronger.

Liberal’s on the other hand believe in quite opposite of the conservative behalf they believe that the rich should be taxed more than the poor since they can afford to pay a little extra money in order to have a greater government “The less government we have, the more liberty we have. ” (Amy). They also approach with saying that these big businesses should be taxed more and pay a larger amount of income tax from their profits to help support and provide for Medi-Cal, Medic-Aid, and Welfare.

In conclusion regardless on which of side of the political spectrum you stand with; either you are a conservative or a liberal, at the end you center all your opinions to your own political beliefs based on your own personal ethics.
