Cell Division : Mitosis and Its Importance

25 Feb

Mitosis is the process by which mature cell divides into two new cells. Each new cells possesses the same number of chromosomes as the parent cell.
All cells except reproductive cells, divide by means of mitosis.
In plants, mitosis is actively carried out at the ends of plant shoots and roots.

 

 

Importance of Mitosis:

1. Mitosis produces new cells for :

(a) growth

(b) replacing aging and damaged cells.

2. Mitosis enables organisms to reproduce themselves:

(a) by asexual reproduction e.g binary fission in amoeba and budding in yeast.

(b)  by vegetative reproduction e.g growing tapioca using its stem, growing lotus using its rhizome and growing bryophllum using its leaf.
