Overview of the 3 types of cell division Mini-Quiz Review Overview of the 3 types of cell division

There are 3 types of cell division: Binary Fission- Prokaryotic cell division. One bacterium splits into two. NO NUCLEUS Mitotic Cell Cycle- Eukaryotic Cell division. One cell with one nucleus divides into 2 identical cells each with a nucleus. 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. Meiosis Occurs in Mitosis- My toes and all body cells (including reproductive organs) Meiosis- My o’s (ovaries) or testes (reproductive organs- gonads)

Mitosis vs. Meiosis Number 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. Meiosis Chromosome Number of Parent Cell Mitosis- Diploid (Regular Body Cell #) Meiosis- Diploid (Regular Body Cell #)

Mitosis vs. Meiosis Chromosome Number of Daughter Cells Mitosis- Diploid (Regular Body Cell #) Meiosis- Haploid (Half the Body Cell #)

Mitosis vs. Meiosis Kind of cell produced Mitosis- Somatic Cells (Body Cells) Meiosis- Gametes (Sex Cells- Sperm and Egg)

Mitosis vs. Meiosis Function Mitosis- Growth and replacement of Cells Meiosis- Sexual Reproduction; Promotes Variation in Offspring
