Mini-Quiz Review Cell Division Intro

Mini-Quiz Review
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. 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
