Question

Cell death is a regulated event within the lie cycle of the organism. In the meantime, apoptosis and necrosis are both used to describe death of a cell. How are they different? Why would this distinction be relevant when we talk about cells?

Answer 1

See differences below - Mitosis meiosis It is called as equational division because the number of chromosomes in daughter cell and mother cell are equal to each other it is called as reductional division because the number of chromosomes in daughter cell is half that of the mother cell It keeps the ploidy level same (if parental cell is 2n, then daughter cell will also be 2n) it reduces the ploidy level to half (if parent cell is 2n the daughter cell will be It occurs in somatic cells of the body for normal growth and maintenance of the body it occurs in germinal cells of the body and give rise to gametes It does not leads to variation it leads to recombination and crossing over which leads to variations

Mitosis	Meiosis
There is no pairing of chromosomes in this type of cell division.	Homologous chromosomes pair with each other to exchange genetic material. The exchange of genetic material is referred to as recombination or crossing over.
It has only one cycle, the four stages are prophase,metaphase, anaphase and telophase.	It has two cycles, meiosis 1 and meiosis 2. Each cycle has four stages. Meiosis one has prophase 1, metaphase 1, anaphase 1 and telophase 1. Meiosis 2 has prophase 2, metaphase 2, anaphase 2 and telophase 2.
