1. Cell Division

2. 1) Binary Fission: division of a prokaryote cell into 2 identical offspring Binary Fission a) Chromosome are copied b) Cell enlarges c) Cell Membrane develops between the two chromosomes

4. 1) Mitosis: cell replication to produce cells identical to the original Mitosis 2) Meiosis: production of gametes (egg/sperm cell), that contain half the organisms genetic info. Meiosis

5. 1) Cell Cycle: life of a cell from its origin in the division of a parent cell until its own division into 2 a) Interphase- preparation for Mitosis b) Mitosis- nuclear division c) Cytokinesis- cytoplasmic division

7. 1) Interphase: 3 steps that will prepare the cell for cell division a) G 1 phase: Growth of cell b) S phase: DNA Replicated c) G 2 phase: Growth of cell d) G 0 phase: Dormant

9. 1) Prophase: a) Nuclear membrane disappears b) Replicated DNA coils into a chromosome c) Centrosomes move towards poles of cell d) Spindle Fiber extend

11. -Characteristics of Prophase -Spindle Fibers: divides sister chromatids btwn two cells

12. 2) Metaphase a) spindle fibers line chromosomes up in the center of the cell at metapheseal plate

13. 3) Anaphase a) chromosomes separate equally and move toward poles of the cell

14. 4) Telophase a) Spindle fibers break off b) chromosomes loosen to form chromatin c) Nuclear membrane forms around chromosomes

15. 1) Division of the cytoplasm 2) Animal Cells: cleavage furrow forms in btwn each set of nuclei 3) Plant Cells: cell plate forms in btwn each set of nuclei
