Meiosis and Mitosis
Carly, Grace, Kellen, Emma

2. Meiosis Produces Haploid gametes (sperm and egg cells)
Reduced genetic material by half
Used in sexual reproduction

3. Mitosis Creates diploid cells (not sex cells)
Daughter cells are identical to the mother cells
Used for growth and repair

5. Mitosis Meiosis Number of divisions 1 2 Number of daughter cells 4
Results
identical diploid (2n) daughter cells
Reduction division results in haploid (n) cells
Genetically identical?
Yes No
Chromosome #
Same as parent
Half of parent
Where
Somatic cells
Sex cells
When
Throughout life
At sexual maturity
Role
Growth and repair
Sexual reproduction

6. Phases of mitosis
Interphase
Prophase
Metaphase
Anaphase
telophase

7. Prophase Chromation condenses into chromosones
Centriole separate and a spindle forms
Nuclear envelope breaks down

8. Metaphase Chromosones line up across the center of the cell
Each chromosome is connected to a spindle fiber at its centromere

9. Anaphase
Sister chromatids separate into induvidual chromosomes and are moved apart

10. Telophase Chromosomes gather at opposite ends of the cell
Chromosomes lose their distinct shapes and two nuclear envelopes are formed
