MItosis is the stage in which cells continue to divide and re-divide. Meiosis occurs when cells divide into a "complete" cell in its final form and function that will no longer subdivide.
What Is The Diffrence Between Mitosis And Meiosis?
In generic terms, mitosis occurs in all of our cells (the somatic cells) while meiosis occurs in the gamete cells (sex cells). Thus, if you cut yourself, the skin that grows over it grows because the skin tissue cells (somatic in nature) are undergoing mitosis to produce cells identical to the original cells.
While when an ovum is produced, or a sperm, it does so by meiosis.
So, why the difference. Firstly, mitosis produces two daughter cells from one parent cell whereas meiosis produces 4 daughter cells from one parent cell. Secondly, the number of chromosomes in one daughter cell resulting from mitosis is the same as the parent call (diploid number). The number of chromosomes in one daughter cell resulting from meiosis is half of that in the parent cell (haploid number). There is actually a reason for that. The gamete cells need to have a haploid number of chromosomes because two gametes join together to form a zygote which forms a whole new organism. Thus, if two gametes have half the number of chromosomes, the number would be complete in the zygote which then goes under a series of mitotic divisions to form a new organism.
Then, mitosis has only one stage while meiosis occurs in two stages: Meiosis I and meiosis II. In both mitosis and meiosis I, the DNA duplicates and results in the same number of chromosomes when the cell divides. However, there is no DNA duplication in meiosis II so that the daughter cells that result now have half the number of chromosomes.
In meiosis, the homologous chromosomes pair up in prophase I. This does not happen in mitosis. Also, mitosis does not see fragments of chromosomes crossing over to each other because the result of mitosis is identical genetic make up of daughter cells. In meiosis, this is important because this creates differences in the genetic make up and characteristics between all the offspring. If this did not happen a couple would have children who would always look exactly like each other.
That is about it!

That is about it!
Meiosis involves a diploid cell dividing into two haploid cells. This is what happens when sperm is made in the testes and eggs made in the ovaries. On the other hand mitosis is 'normal cell division', the cell makes an exact copy (clone) of the full DNA (2n).
Yea what he said! ^the difference is one divides and on going and the other does too but only like once.
Umm well I don't know I'm to blond to know haha I'm funny and hot
The difference between mitosis and meiosis is that mitosis produces diploid cells while meiosis produces haploid cells.
