Document Summary
Distinguish between the different stages of mitosis and identify important structures. Distinguish between mitosis and meiosis in plants and animals. B. meiosis: plant, animal, plant, animal, mitosis. Most multicellular eukaryotes grow in size by an increase in cell size up to a "normal" limit and an increase in cell number in the organism. An increase in cell number is accomplished by mitosis, a process where a diploid (2n) mother-cell nucleus subdivides into two genetically identical diploid daughter-nuclei. In addition to contributing to growth, mitosis also allows new cells to be provided for the "healing" of damaged tissues and the replacement of certain cells that have a short life span, such as blood cells. While mitosis is a nuclear division, there also exists another type of division, which is responsible for the division of the cytoplasm between the two new daughter cells. This type of division is known as cytokinesis.
