Cellular Reproduction

Cellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This is essential in that if a species were not able to reproduce, that species would quickly become extinct. Always, reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring.
(Encarta, 2) In almost all animal organisms, reproduction occurs during or after the period of maximum growth. (Fichter, 16). But in
Plants, which continue to grow through out their lifetime, therefore making the process more complex. Plants' reproduction is usually caused by a stimulant, mostly environmental or

Spindle fibers are barely visible. This phase takes fifty to sixty percent of the time of mitosis. (Biggs, 214) During metaphase, the short second phase of mitosis, the sister chromatids line up along the equator of the cell. Each sister chromatid has its own spindle fiber. Next comes the third phase of mitosis, Anaphase, in which the centromeres break in half, causing each of the daughter chromatids to start to be pulled to different poles of the cell by means of spindle fibers. The spindle fibers pull the daughter chromatids until they reach the poles of the cell. Finally, the last phase of mitosis called Telophase in which the daughter chromatids are fully pulled toward the poles and the nuclear envelope begins to reappear, the cell also begins to cleave, usually in the spot where the chromatids lined up in metaphase. After mitosis is complete, cytokinesis occurs, cytokinesis is the process in which a cell’s cytoplasm is split into two equal parts, therefore causing the mother cell to split into two daughter cells. In plants, however, cytokinesis is replaced by the placing of a cell plate on the metaphase “equator”
Mitosis is a process that guarantees better cellular work.

The two new daughter cells will carry out the same functions and cellular processes as the parent, ensuring that the two cells will carry out twice as much as the original cell. Mitosis often occurs in multicellular animals and plants, not making the organism
