cell division
is the process by which new cells are formed for growth, repair and replacemenet in the body
mitosis
manner in which single somatic cells divide to form new daughter cells identical to the parent cell. 23 pairs(46) of chromosomes
meiosis
special type of cell division that occurs in the production of the gametes (eggs & sperm. 23 total chromsomes
4 stages of mitosis
prophase, metaphase, anaphase, and telophase
interphase
period between active cell division.
prophase
the chromatin shortens, thickens, and becomes tightly coiled to form chromosomes
metaphase
chromosomes align themselves along the center of the cell. Chromosomes are are most clearly visable.
anaphase
centromeres separate so that each chromatid now becomes a chromosome. There are two sets of chromosomes in the cell. the two chromatids migrate to the opposite ends of the cell. The cytoplasm starts to divide.
telophase
chromosomes reach the centrioles at the end of the cell, a new nuclear membrane orms around them. Spindle fibers disappear. The chromosomes start to uncoil.
cytokinesis
division of cytoplasm which occurs during telophase
