Cell division : All cells reproduce by division and division of cells into daughter cells is called cell division. There are three types in animal cells: 1.Amitosis - Direct Division 2.Mitosis - Indirect Division 3.Meiosis - Reduction Division

Formative assessment: a student who expressed his opinion in the correct sentence and actively participated in the discussion “Well done!”

Amitosis is the major means of reproduction in bacteria, unicellular protozoa and unicellular fungi like yeast. The multiplication process in vertebrate foetal membranes is also the amitosis.

Process of Amitosis: -

The following steps are involved in the process of amitosis:

i) Due to auxetic growth the cell is being enlarged.
ii) The nucleus is enlarged and ultimately forms a dumbbell-shaped structure with the appearance of a median constriction.
iii) On the median part of the cell membrane two constrictions are appearing.
iv) The constriction of the nucleus gradually grow deeper and divides the nucleus into two daughter nuclei without the formation of any spindle fibre.
v) The invaginations of the cell also move inwards and the parent cell is divided into two equal size of daughter cells.

Advantage of Amitosis: -In this process the cell division is completed within a short time. The Amitosis is the major means of reproduction in lower organism like yeast, bacteria etc.

Disadvantage of Amitosis: -

In this process of cell division there is no possibility of genetic recombination and there is a possibility of expression of unwanted recessive genes.
