1. Mitosis
Cell Reproduction

2. Mitosis Notes
Asexual Reproduction – offspring are produced that are genetically identical to the parent
Mitosis – the asexual reproduction process of cell division

3. Mitosis Notes During cell division …
It is essential that the DNA is replicated
The number of chromosomes NEVER changes
Each daughter cell gets its own copy of the DNA

4. The Phases of Mitosis Interphase Prophase Metaphase Anaphase Telophase
Cytokinesis

5. MITOSIS: Starts with one cell Chromosomes are copied
Daughter cells are IDENTICAL to the original cell

6. Interphase
What happens?
DNA replicates
Cell looks normal

7. INTERPHASE

8. Prophase What happens? Nuclear membrane disappears Chromosomes appear
Centrioles begin to move

9. PROPHASE

10. Metaphase What happens?
Spindle fibers line the chromosomes up in the middle of the cell

11. METAPHASE
Chromosomes lined in center of cell
Spindle fibers attach

12. Anaphase
What happens?
The spindle fibers pull the chromosomes apart at the middle

13. ANAPHASE
Chromosomes pulled to opposite ends of the cell by spindle fibers

14. Telophase What happens? Nuclear membrane reappears
Chromosomes disappear
The cell begins to be pinched in the middle

15. New cell wall is starting to form
TELOPHASE
New cell wall is starting to form
early-TELOPHASE
late-TELOPHASE

16. Cytokinesis What happens? The cell is pinched in half
Two identical cells are made

17. CYTOKINESIS
Two new daughter cells that are IDENTICAL to the original cell!
