Title: Using diagrams, compare the structure and function of prokaryotic and eukaryotic cells. All living things are made up of cells. They contain a nucleus that controls and executes their activities. Cells are divided into two main categories based on whether or not they contain a nucleus. They are: Prokaryotic cell Eukaryotic cell Simplest and oldest Complex and evolved from prokaryotes Single cell Single cell or multicellular Lacks a nucleus Contains a nucleus Contains a cell wall (peptidoglycan) Contains a cellulose cell wall only in plant cells Small scattered ribosomes throughout the cytoplasm. No mitochondria therefore take place on a fold of the cell membrane. They release an enzyme called carbonic anhydrase that allows water to enter the bloodstream and carry carbon dioxide to the lungs where it is expelled. Additionally, they help control blood pH by acting as an acid-base buffer. Sperm Structure: The sperm is a male reproductive cell that forms in the male reproductive system. They are very small, about 0.002 inches long, because they contain a long tail-like flagellum. The main function of the sperm is to carry genetic information from the male parent and form a new embryo when combined with an egg. The shape of the sperm is quite simple, like a snake structure that includes a small egg head, neck, midpiece, and tail. Head: It is spherical in shape and consists mainly of a large nucleus and a cap-shaped structure called an acrosome. The nucleus contains DNA and nuclear proteins responsible for transmitting the male's hereditary traits. The acrosome is filled with digestive enzymes (hyaluronidase and acrosin) which facilitate the penetration of sperm into the egg...
