We will begin by studying the organelles found in a typical eukaryotic cell. In addition, we will examine cells from different types of organisms both live and dead. For example, we will compare a variety of different plant and animal cells. Using these organisms, we will have an opportunity to see how cells react to their environment. In addition, we will watch them ingest and digest food.
Cell biologists continue to study the workings of cells.
Studies of cell organelles have led to the causes of some diseases. For example, Tay-Sachs disease which damages the nervous system, is due to defective lysosomes. Basic research on the function of cells has led to a variety of improvements in health care. For example, an understanding of hormone release, binding, and action has enabled pharmacologists to design a medication for high blood pressure. New therapies for the treatment of cancer and other illnesses are often discovered through cell testing.
