SN.	Point of distinction	Mitosis	Meiosis
1.	Occurrence	It occurs in all somatic cells or vegetative cells (except gamate formation)	It occurs in germ or reproductive cells.
2.	Number of cells produces	A diploid/haploid cell produces two identical diploid/haploid cells, so called equational division.	A diploid cell produces four haploid cells. Hence, it is called reduction division.
3.	Phases or stages	Mitosis completes in 4 stages-prophase, metaphase, anaphase and telophase.	Meiosis is divided into Meiosis-I and Meiosis-II and each has 4 stages
4.	Prophase	Duration of Prophase is short and not divided into sub-phases.	Duration of Prophase-I is long and divided into 5 sub-phases-leptotene, zygotene, pachytene, diplotene and dikinesis
5.	Metaphase	Chromosome occurs as dyads in metaphase.	Chromosome occurs as tetrads in metaphase-I
6.	Metaphasic plate	Centromeres forms single metaphasic plate	Centromeres forms two metaphasic plate
7.	Homologous chromosome	Absent	Present
8.	Synapsis and crossing over	Absent	Occurs
9.	Anaphase	During anaphase chromosomes are having single chromatids	During anaphase homologous chromosomes occurs and have two chromatids
10.	Types of cells	It occurs in both haploid and diploid cell.	It only occurs in diploid cell.
11.	Mode of reproduction	Asexual	Sexual
