TB Notes Chapter 11- The Cell Cycle - Cell Division : new cells arise thru the division of preexisting cells. - Gametes: reproductive cells in males and females (including sperm and eggs). - Somatic Cells : body cells; all other cells in cells besides reproductive cells. - In animals, meiosis leads to the production of eggs and sperm. - Mitosis is responsible for producing somatic cells. - Meiosis : in sexually reproducing organisms, a special two-stage type of cell division in which one diploid (2 n ) parent cell produces four haploid ( n ) reproductive cells (gametes); results in halving of the chromosome number. - Mitosis: a division of the genetic material that produces daughter cells that are genetically identical to their parent cell. - Cytokinesis: (cell movement) the division of the cytoplasm into the two daughter cells. - Mitosis and Cytokinesis are responsible for: 1. Growth: all cells in the body can be traced back thru a series of mitotic divisions to a single feritlized egg. 2. Wound Repair: cells that reapair wounds are generated from mitosis and cytokinesis 3. Reproduction: asexual reproduction
