Types of cell division:
Cell division is of three types: (i) Amitosis (ii) Mitosis and (iii) Meiosis.
Amitosis: This type of cell division occurs in unicellular prokaryotic organisms like Bacteria, Yeast etc. In this division, at first the nuclear materials are directly spitted into two portions and then the cell divides into two from the middle region. As a result, from one cell there’ develops two.
Mitosis: Mitosis is a type of cell division by which a eukaryotic cell divides into two by a special method. In this process, the nucleus and chromosome are divided once and the number, structure and properties of chromosome in the newly formed cell remain just alike the mother. Mitosis is also termed as equational division. Normally this division occurs in somatic cell. As a result of this division, the plant and animal increases in length and breadth. Mitosis occurs in all meristamatic cells of plants.
Meiosis: Meiosis is a type of cell division by which a Eukaryotic cell divides into four cells by a special method. In this process the nucleus divides twice but the chromosome divides once. The number of chromosome in the newly formed daughter cell reduces to the half the number of mother cell. As the number of chromosome reduces to half this process is also termed as reduction division.
