1. Cell Reproduction “Mitosis”

2. Somatic (Body) Cell Life Cycle (everything but eggs and sperm)
INTERPHASE
(Everything ‘in between’ mitotic cell divisions.)
G1: Newly formed cell grows up and does its job.
S Phase: Cell starts copying its DNA
G2: The cell continues to do its regular job, but more slowly and important organelles are duplicated.
MITOSIS
Cell divides into two identical daughter cells.
Prophase, Metaphase, Anaphase and Telophase

3. MITOSIS Asexual reproduction of cells.
Also called cloning and vegetative propagation.
Results in two, identical daughter cells.
Necessary for:
Maintenance
Growth
Reproduction in asexual species

5. PMAT 4N Cell PROPHASE Condensed chromosomes Bye bye nuclear envelope
Centrioles hook spindle fibers to chromosomes

6. PMAT 4N Cell METAPHASE Chromosomes line up at the plate.
Sister Chromatids
Homologous Chromosomes

7. 4N Cell
PMAT
ANAPHASE
Spindle fibers pull sister chromatids apart toward centrosomes.

9. PMAT 2, 2N Cells TELOPHASE Hello nuclear envelope!
Good bye spindle fibers!
Chromosomes decondense (is this a word?)
Cell plate forms in plants/ cell membrane pinches off in animals.

10. Cytokinesis PLANTS: ANIMALS: Cell wall forms between new cells
New plasma, or cell membrane forms around new cells.
