Q
Meiosis
A
Variation in daughter cells 2 cell divisions, 4 different haploid sex cells Haploid cell (23 chromosomes) n Two cell divisions 4 different (sex) cells (gametes) FOR sexual reproduction Two parents (one male one female) Takes more time
1
Q
Mitosis
A
1 cell division-2 identical diploid cells Exact replication of parent cell Diploid cell 23 pairs of chromosomes 2n One cell division 2 identical cells Asexual reproduction One parent Less time Used for growth, repair, and replacement
2
Q
Extra (sex cells)
A
Girls- produce 1 egg and 3 germ cells
Guys- 4 sperm cells
3
Q
Stages of mitosis
A
Interphase (nothing happens) Prophase Metaphase Anaphase Telophase Cytokinesis (cytoplasm separates)
4
Q
Interphase 1
A
Chromosomes duplicate
5
Q
Prophase 2
A
Nuclear membrane dissolves
6
Q
Metaphase 3
A
Chromosomes line up in the middle of cell for division
7
Q
Anaphase 4
A
Chromosomes move to opposite ends of cells
8
Q
Telophase 5
A
Two new nuclei (end of mitosis)
9
Q
