1. Cell Cycle 1/5/2011

4. Binary Fission Binary fission produces daughter cells with DNA identical to the parent.

5. Regeneration When an organism is able to regrow part of their organism or most of an organism from just a section. A part of the nervous system must be included for regeneration to occur. In such an organisms cells are able to differentiate (change into cells of different function).

8. What is the longest part of the Cell Cycle and why?

9. 1. Interphase –includes G1, S, &G2 2. Mitosis Prophase (Pieces) Metaphase (Middle) Anaphase (Apart) Telophase (Two) ///Cytokinesis Cell Cycle

10. Stage One: Interphase Longest stage Cell grows to its mature size [G1], makes a copy of its DNA (replication/synthesis) [S], continues to grow and prepares to divide [G2]. The Cell Cycle

11. Phases of Mitosis Prophase Chromatin condenses and becomes fully visible Nuclear membrane disappears Centrioles move to opposite ends of the cell Spindle fibers stretch across the cell Prophase (Hint: Pieces)

12. Phases of Mitosis Metaphase Chromosomes line up Centromeres become attached to spindle fibers Metaphase (Hint: Middle)

13. Phases of Mitosis Anaphase Chromatids separate and move away from each other to opposite ends of the cell Anaphase (Hint: Apart)

14. Phases of Mitosis Telophase A nuclear membrane forms around each mass of chromosomes Telophase (Hint: Two)

15. Cytokinesis Cytoplasm divides Each daughter cell has the same number of chromosomes as the original parent cell The Cell Cycle

16. What parts of the cell cycle can you see here?
