1. Compare and contrast, prokaryotic cell, eukaryotic cells and viruses. (30 points) We are unsure weather or not viruses are considered living. They do not grow or develop, obtain or use energy, or respond to the environment. These are all requirements to be living. They don’t contain cells and are not typically considered cells. Their nucleic acid is either DNA or RNA. They have no nucleus, ribosomes or mitochondria, no binary fission or mitosis/meiosis. Their outer surface is protein capsule. Viruses require a host organism in order to live and reproduce. Unlike viruses both prokaryotic and eukaryotic cells are both living. Eukaryotic cells are what we are made up of. Animals are also made up of these cells. They are made up of membrane enclosed organelles including a true nucleus containing a nuclear membrane and nuclei. These cells can be either single-celled or multi-celled. These cells contain flagella that is complex and consist of multiple microtubules. In Eukaryotic cells the polysaccharide covering is only present in some of the cells that do not contain a cell wall, cell wall not always present when it is it is chemically simple. The plasma membrane in the cell contains sterols and carbohydrates which act as receptors. Other organelles in the cell are; cytoplasm which contains cytoskeleton, large and small ribosomes, chromosomes that contain histones and are multiple linear (double helix). Eukaryotic cells divide by mitosis and sexual recombination occurs by meiosis. Prokaryotic Cells are what make up things like algae or other plants. They contain no nucleus or membrane-enclosed organelles. Usually in this cell a cell wall will be present. The flagella consists of only two protein building blocks and the polysacch... ... middle of paper ... ...ons can save your child’s life” in the first point “Because of advances in medical science, your child can be protected against more diseases than ever before. Some diseases that once injured or killed thousands of children, have been eliminated completely and others are close to extinction– primarily due to safe and effective vaccines. Polio is one example of the great impact that vaccines had have in the United States. Polio was once America’s most-feared disease, causing death and paralysis across the country, but today, thanks to vaccination, there are no reports of polio in the United States” These parents have got to realized that one of those deadly diseases is only a plane ride away! Vaccinating children should be required before the child enters school, so we can not only save our children but so we can protect others we care about and generations to come.
