Cell division is an important process of life.
It is present in almost all the form of living beings except in few cells like nerve cells of animals.
This cell division is of two types as mitosis and meiosis.
Before going to differences, it is important to read the details on mitosis and meiosis
|Occurrence||It is occurs in both Haploid cells and diploid cells||It occurs only in diploid cells.|
|Type of cell involved||All body cells or vegetative cells or somatic cells are involved.||It occurs only in reproductive cells or germinal cells.|
|Nucleus division||Nucleus divides once||Here nucleus divides twice to produce 4 nucelii|
|Similarities of daughter cells||Daughter cells are identical to mother cells||Daughter cells are not identical|
|number of cell formed.||Two daughter cells are formed.||Four daughter cells are formed.|
|Prophase||Prophase is simple||Prophase is complicated with many steps.|
|Chromosome pairing||Chromosomes do not pair||Homologous chromosomes (similar) pair to form bivalent one's.|
|Chiasmata and crossing over||Chiasmata is absent, Also there is no crossing over||Chiasmata present . Crossing over between non-sister chromatids occurs.|
|Centromeres||Centromeres undergo divison in anaphase||centroemeres do not divide in anaphase-1 but divide in anaphase-2|
|Chromosome number in daughter cells||Chromosome number in daughter cell is unchanged.||Chromosome number is reduced to half of the parent cell.|
|Time duration for process||The entire cell divion is short comparatively.||Duration of cell divison is very large as it involves many steps..|
|Uses||For growth of body and in lower forms like bacteria, to multiply organism numbers.||To help in gamet formation for sexual reproduction.|
