1. Cell Reproduction

2. The Cell Cycle
Interphase- 90% of a cells life is spent in this phase (a period of growth and development)
During interphase, a cell duplicates its chromosomes and prepares for cell division.

3. The Cell Cycle
2. Mitosis- process in which the nucleus divides to form two identical nuclei

4. Stages of Mitosis Prophase:
Nucleolus and nuclear membrane are removed.
Centrioles move to opposite ends of the cell
Spindle fibers begin to stretch across the cell

5. Stages of Mitosis
b. Metaphase: Pairs of chromatids line up across the middle of the cell

6. Stages of Mitosis c. Anaphase: i. Each centromere divides
ii. Each pair of chromatids separates and moves to opposite ends of the cell.

7. Stages of Mitosis
d. Telophase: Spindle fibers disappear and a new nucleus forms

8. Stages of Mitosis
e. Cytokinesis: End of mitosis, resulting in two separate cells.

9. Reproduction
Asexual reproduction- a new organism is produced from one parent organism.
An organism with no nucleus divides into two identical organisms by fission
Budding- a small, exact copy of the adult grows from the body of the parent
In regeneration, a whole new organism grows from each piece of the parent

10. Asexual Reproduction Starfish regeneration of arms
Binary fission of bacteria
Potato budding
