1. Cell Division
A cell grows in size by increasing both the size and the number of its cells. Then 2 grow and divide, forming and so on.
Cell Cycle: The regular sequence of growth and division that cells undergo
Cell cycle is also known as the Mitosis cycle.
Asexual Reproduction – Mitosis
The process in which the nucleus divides to form two new nuclei

2. Three reasons why cells reproduce by asexual reproduction: 1. Growth 2
Three reasons why cells reproduce by asexual reproduction: Growth Repair Replacement
Cells that reproduce by asexual reproduction reproduce constantly.

3. Mitosis Cycle Three stages: 1. Interphase 2. Mitosis Prophase
Metaphase
Anaphase
Telophase
3. Cytokinesis

4. Interphase occurs before mitosis begins
Interphase is considered to be the 'living' phase of the cell, in which the cell obtains nutrients, grows to full size, reads its DNA, and conducts other "normal" cell functions.

6. Stage 2: Mitosis Mitosis begins – cells begin to divide
Scientists divide mitosis into 4 parts, or phases:
Prophase
Metaphase
Anaphase
Telophase

7. Phase 1 Prophase
Centrioles (or poles) appear and begin to move to opposite end of the cell.
Spindle fibers form between the poles.
Nuclear envelope breaks down
Centrioles
Sister chromatids
Spindle fibers

8. Prophase Plant Cell Animal Cell Spindle fibers Centrioles
Photographs from:

9. Phase 2: Metaphase
Chromosomes attach to the spindle fibers at its centromere (center).
The Chromosomes line up across the center of cell.
Spindle fibers

10. Metaphase Plant Cell Animal Cell
Photographs from:

11. Phase 3: Anaphase The chromosomes split in half.
Each side of the newly split chromosome move to opposite ends of the cell.
Centrioles
Spindle fibers

12. Anaphase Plant Cell Animal Cell
Photographs from:

13. Phase 4: Telephase Two new nuclei form.
Chromosomes appear as chromatin (threads rather than rods).
A new nuclear envelope forms around each region of chromosomes.
Mitosis ends.

14. Telophase Plant Cell Animal Cell
Photographs from:

15. Stage 3: Cytokinesis occurs after mitosis
Final stage of the cell or mitosis cycle.
Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes.

16. Typical Cell cycle in an animal cell

17. Time to complete cycle?
How long it takes for a cell to go through mitosis depends on the cell. A human liver cell, for example, completes one cell cycle in about 22 hours.
