2 M Phase (division) Interphase G1 Phase G2 Phase S Phase Growth DNA & Chromosome Replication Cells Spend Most of the Time in Interphase

3

4 Mitosis  Produces New Body (Somatic) Cells  Growth of Multi-cellular Organisms  Form of Asexual Reproduction (Genetic Information is not shared)  Results in Identical Daughter Cells

5 Prophase Replicated chromosome Nucleus dissolves Centrioles migrate

6 Metaphase Chromosomes line up on “equator” Centrioles at “poles” Spindle fibers form

7 Anaphase Replicated chromosomes separate Centrioles at “poles” Spindle fibers “pull”

8 Telophase Chromosomes gather together Nucleus re-forms Cytokenesis begins

9 Interphase Two identical daughter cells same number of chromsomes as parent cell (diploid) begin to carry out normal cell functions chromosomes begin to replicate

11 Meiosis  Produces Gametes  Results in Sperm, Egg, or Pollen  Necessary for Sexual Reproduction (Genetic Information is shared)  Results in Daughter Cells with Half the Amount of Genetic Information

12 Prophase I Replicated chromosome Nucleus dissolves Centrioles migrate

13 Metaphase I Pairs of chromosomes (homologs) line upon “equator” Centrioles at “poles” Spindle fibers form

14 Anaphase I Pairs of chromosomes (homologs) separate from each other Centrioles at “poles” Spindle fibers pull homologs apart

15 Telophase I Chromosomes gather together Nucleus re-forms Cytokenesis begins

16 Interphase I Two new cells after 1st division half number (haploid) of chromosomes in each daughter cell a second cell division begins

17 After 2nd division Four total daugther cells each daughter cell with haploid number of chromosomes these cells are called gametes (sex cells) in animals: male - sperm, female- ova (egg) in plants: male - pollen, female - egg

18 MitosisMeiosis Produces somatic (body) cells diploid number of chromosomes in daughter cells one cell division resulting in two daughter cells replicated chromosomes individually line up during metaphase genetic information in daughter cells identical to that of parent cell Produces gametes (sex) cells haploid number of chromosomes in daughter cells two cell divisions resulting in four daughter cells replicated chromosomes line up in pairs (homologs) during metaphase genetic information in daughter cells different to that of parent cell
