1. Mitosis and Meiosis

2. mitosis
A process of cell division that forms two new nuclei, each of which has the same number of chromosomes.
Occurs in eukaryotic cells

4. meiosis
A process of cell division during which the number of chromosomes decreases to half the original number, and results in 4 new haploid cells.
Produces sex cells (sperm & egg)
Haploid: half the original number of chromosomes

6. Meiosis Meiosis animation: 4 daughter cells produced
Each daughter cell has half the chromosomes of the parent
2 sets of cell division involved
Same steps as in mitosis
Meiosis animation:

7. This may help you remember these terms:
MITosis takes the cell and Makes It Two (diploid=n)
Meiosis has to do with sex
From the cell’s point of view:
mITosis results in Identical Twins
mEioSis results in Egg and Sperm (haploid=2n)
