27. Explain the major differences in the products of cell division between mitosis and meiosis. What are the primary functions of each type of cell division?detail answer

Expert Solution

Mitosis	Meiosis
This occurs in somatic cells of haploid as well as diploid organisms.	occurs in the reproductive cells of diploid organisms only.
it produces two daughter cells	it produces four daughter cells
it is completed in one division	it is completed in two successive divisions.
it is the equational division	it is the reductional division
genetic constitution of daughter cells remains the same.	the genetic constitution of daughter cells becomes different.
no synapsis takes place	synapsis occurs during prophase 1
no crossing over takes place.	crossing over takes place in prophase 1

functions of mitosis

help in the growth of animals and plants.
it replaces old and dead cells.
repairs damaged and wounded tissues of animals and plants.
helps un asexual reproduction in unicellular organisms.
maintains the same number of chromosomes in daughter cells

functions of meiosis

I sex cells(gametes), the chromosome number is halved so that on fertilization the normal number (2n) is restored.
helps in mixing up genes which increases the genetic vigor.
helps in causing variations which further leads to evolution.
