Overview of the 3 types of cell division

There are 3 types of cell division:

1. Binary Fission- Prokaryotic cell division. One bacterium splits into two. NO NUCLEUS

2. Mitotic Cell Cycle- Eukaryotic Cell division. One cell with one nucleus divides into 2 identical cells each with a nucleus.

3. Meiotic Cell Cycle- Eukaryotic Cell Division. One cell with one nucleus divides into 4 different/distinct cells each with a nucleus containing half the genetic information.

Mitotic Cell Cycle vs Meiotic Cell Cycle

Mitosis vs. MeiosisOccurs in

Mitosis- My toes and all body cells (including reproductive organs)

Meiosis- My o’s (ovaries) or testes(reproductive organs- gonads)

Mitosis vs. MeiosisNumber of cells produced per parent cell

Mitosis- TWO

Meiosis- FOUR (in Females only 1 of 4 will be a viable/usable egg, in Males all 4 will be viable sperm)

Mitosis vs. MeiosisChromosome Number of Parent Cell

Mitosis- Diploid (Regular Body Cell #)

Meiosis- Diploid (Regular Body Cell #)

Mitosis vs. MeiosisChromosome Number of Daughter Cells

Mitosis- Diploid (Regular Body Cell #)

Meiosis- Haploid (Half the Body Cell #)

Mitosis vs. MeiosisKind of cell produced

Mitosis- Somatic Cells (Body Cells)

Meiosis- Gametes (Sex Cells- Sperm and Egg)

Mitosis vs. MeiosisFunction

Mitosis- Growth and replacement of Cells

Meiosis- Sexual Reproduction; Promotes Variation in Offspring
