Difference between cleavage and normal Mitosis

Difference between cleavage and normal Mitosis:– cleavage– site of occurrence of cleavage is zygote or parthenogenetic egg, it is very Rapid process for shorter duration in which daughter cells which are formed have smaller size and growth are not taking place whereas normal Mitosis occurs in most of somatic cells for a longer period and daughter cells formed go to growth phase.

Difference between cleavage and normal Mitosis

Cleavage is define as in developmental biology, cleavage is the division of cells in the early embryo. The zygotes of many species undergo rapid cell cycles with no significant overall growth, producing a cluster of cells the same size as the original zygote. Mitosis is the division of a cell of the body that results in two cells, each with the same number of chromosomes as the original cell.

Now understanding the difference between cleavage and normal mitosis in given table

◆ Cleavage:-
1) cleavage is fractionating process in which daughter cells which are formed become a smaller and smaller

2) site of occurrence of cleavage in zygote or parthenogenetic egg

3) during cleavage interphase of shorter period

4) the daughter cells which are formed in cleavage process in which growth are not taking place

5) it consume more amount of oxygen compare two mitosis process because it is very Rapid process

6) daughter cells decrease in size

7) DNA synthesis is faster as compared to Mitosis

8) nuclear cytoplasmic ratio in cleavage process is increases compare to mitosis process

◆ Normal mitosis:-
1) mitosis is equational cell division in which formed daughter cells undergo growth phage during interphase and attain the size of parent cell

2) mitosis occurs in most of somatic cells

3) in mitosis process interphase is of longer period

4) growth occurs during interphase

5) oxygen consumption is low as it is slow process

6) size of daughter cells remain same after growth

7) DNA synthesis is slower in case of Mitosis compare to cleavage process

8) nuclear cytoplasmic ratio remains same
