|
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
|
