Every cell definitely has division process. The purpose of cell division is to produce new cells. Each of the cells carries a complete genetic information in DNA.
The Types of Cell Division
There are three general types of cell division, amitosis, mitosis, and meiosis. Amitosis occurs in prokaryote, while mitosis and meiosis occur in eukaryote.
|Amitosis in bacteria|
Amitosis or also known as binary fission is a type of direct cell division without having been through certain stage. In this process, somatic cell is division into two parts, each of which can grow into new complete organism. Amitosis in microbe occurs either horizontally (e.g. Paramecium) or vertically (e.g. Euglena).
Mitosis produces 2 daughter cells which are genetically identical. It means, the two daughter cells have similar genetic composition with their parents.
Meiosis produces 4 haploid (n) daughter cells that come from diploid parents (2n). In the process, each of daughter cells has half chromosome of the parental cells.
Mitosis and meiosis occur in several stages' The stages will be further discussed after learning the following cell cycle.
