Mitosis produces two Diploid Cells while Meiosis produces four haploid cells. The purpose of Mitosis produces new body cells and does not allow for genetic variation, while meiosis allows genetic variation through multiple processes.
Meiosis produces sex cells (sperm) , which are key in reproduction of multi-cellular organisms. Each new cell contains half of the number of chromosomes.
Meiosis has 2 cellular divisions, while mitosis only has one.
They are both necessary to support life, and they both produce Diploid cells in the first division.
Also, from a similar topic in Yahoo Answers (Which has a much better explanation) :
Mitosis is a type of cell division to produce 2 X genetically identical diploid (2n) cells for growth and repair. Mitosis occcurs in somatic cells (normal body cells. Prior to mitotic division DNA is replicated to produce two identical chromatids attached by a centromere. This is essential so that each new daughter cell formed receives one copy of each chromosome. (One division)
Meiosis only occurs in the sex organs to produce 4 X haploid (n), genetically different, gametes for sexual reproduction.
Meiosis consists of two divisions:
Meiosis I halves the number of chromosomes to give 2 X haploid cells.
Meiosis II doubles the number of cells to give 4 X haploid gametes.
Two processes during meiosis I increase variation .
In prophase I homomolgous chromosomes cross over at points called chiasmata and exchange genetic material.
In metaphase I the chromosomes line up along the equator in pairs. This is called random assortment where maternal and paternal chromosomes are arranged at random.
Both of these increase variation to produce four genetically different gametes at the end of meiosis II
DNA replication only occurs once, before Meoisis I.

∙ 9y agoDuring mitosis cells divide producing two cells that are diploid somatic cells which are genetically identical. During meiosis there are four daughter cells, each with a haploid set of chromosomes. These homologous chromosomes pair up, called crossing over, and create genetic diversity The haploid gametes produced during meiosis create daughters who are genetically different.

∙ 14y agoMitosis makes two identical cells.
Meiosis makes four different cells.
Mitosis makes two cells with exactly the same number of chromosomes.
Meiosis makes four cells with half the number of chromosomes
Mitosis only takes one step.
Meiosis takes two steps.

∙ 7y agomitosis is defined as the no. of chromosomes are distribute half in numbers.so this is also called as 'equational cell division'.

∙ 12y agoMitosis produces two diploid daughter cells with identical chromosomes.
Meiosis produces four haploid daughter cells with non-identical chromosomes.

∙ 6y agomeiosis produces four cells, but mitosis produces two cells. apex :D

they both involve duplicating chromosomes

What is the terms refers to a region of a chromosome that has a specifiic function?
The region of chromosome that is generally thought of as the unit of function is the "gene". Genes are composed of both a "coding region"--that sequence that tells the cell's machinery what the protein will be--and a "regulatory" region, which tells the cell when to turn on the coding region to make the protein.
Which is true about a daughter cell produces by mitosis?
it can function independently
What Variations of homologous genes that result in differences in structure and function are?
Alleles
How do chromosomes function in a prokaryotic cell?
In a prokaryote there is no designated nucleus and the genetic mass is free floating. As there is one chromosome it is circular.
What is true about a daughter cell producted by mitosis?
it can function independently.

What are the Similarities in turkey vultures and black vultures?
Both vultures and ptarmigan are birds, vertebrates and consumers. But that's where the similarities end. Differences include plumage coloring in bearded vultures and red knots may serve a cosmetic function whereas in rock ptarmigan the function appears to be camouflage. Other differences can be found in the related question below.
Function of a thread like cell?
The thread like structure that contains the genetic cell information is called Chromosome. A chromosome carries the DNA bound proteins that packages and controls the DNA function.
What relates the structure of the Cell to the Cells function?
It's chromosome complement.
