Even though the basic composition of most cells are similar, there are many different types of specialized cells found in various organisms. For this discussion please choose one type of cell to research and describe. Choose one type of cell not yet described by other students (easier the earlier you post!). Do NOT choose eukaryotic, prokaryotic, plant, animal or bacteria cells (the large categories of cells), rather choose a specialized type of cell found in animals (examples: blood, nerve or...
Bacterial cells, such as E. coli, are surrounded by a fluid plasma membrane and enclosed by a rigid cell wall that protects the cell from damage. You will recall that there is no nuclear envelope in prokaryotic cells, but rather a “nucleoid region” with a single chromosome that is continuous (circular), not linear, as in eukaryotes. All of the genes required for basic survival and reproduction are found in the main chromosome. In addition to the main chromosomes, some DNA...
4 The various types of cells making up the structural composition of your body (skin cells, muscle cells, cells of your stomach lining, etc.) are all _________________________________________ cells. The only other class of cells in your body are _______________________________ (sperm and egg cells). 5 Pretend that you are observing a skin cell from a chicken under a microscope. What is the class of cell you are looking at? 6 What is the substance in our bodies that serves as a...
