Question

Compare and contrast what happens in mitosis and meiosis and discuss the importance of each process to a living organism.

Answer 1

mitosis is a multiplicative divison,in this type of cell divison a parent cell(2n) divides in equally same 2 daughter cells,both having chromosome no 2n.this typr of cell divison occurs in case of growth,repairment,etc..but meiosis is a reductional division here a parent cell first produces two daughter cell having half the chromosome no.i.e. n.then these two daughter cells undergo the same process of mitosis,producing 4 new daughter cells.

Answer 2

meiosis only occurs in gonad cells,like testes and ovary.

Answer 3

Maybe these images will help you understand better :)

Answer 4

thanks thomaster :)

Answer 5

joey do you get this?or should i elaborate?

Answer 6

importance of meiosis is it helps keeping our species chromosome no constant,because when a sperm or ova is fertilised,they both have n sets of chromosomes,so after fusion the zygote is again 2n,which will give rise to an adult,so ultimately the no is constant

Answer 7

thank you
