1. SECTION 10.2
Cell Division

2. A) Cell Division in Prokaryotes
Binary Fission:

3. Binary Fission

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

5. C) The Cell Cycle
Cell Cycle: life of a cell from its origin in the division of a parent cell until its own division into 2
Interphase-
Mitosis-
Cytokinesis-

6. Cell Cycle

7. D) Interphase
Interphase: 3 steps that will prepare the cell for cell division
a) G1 phase:
b) S phase:
c) G2 phase:
d) G0 phase:

8. Interphase

9. E) Mitosis Prophase: -Characteristics of Prophase
Nuclear membrane disappears
Replicated DNA coils into a chromosome
Centrosomes move towards poles of cell
Spindle Fiber extend
-Characteristics of Prophase
-Spindle Fibers: divides sister chromatids btwn two cells

10. Prophase

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

12. E) Mitosis
3) Anaphase
a) chromosomes separate equally and move toward poles of the cell

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

14. F) Cytokinesis
Division of the
Animal Cells:
Plant Cells:

15. Cytokinesis

16. Reasons for making a new cell
Goal of the cell Cycle:
