1. Mitosis

2. What is Mitosis?
Mitosis: Cell division involving somatic (non-sex) cells
Involves only diploid cells
Form of asexual reproduction for some life (bacteria & protista, fungi)
End Result: Two genetically identical “daughter cells”

3. The Cell Cycle Defined: Repeating set of events in the life of a cell
1) Interphase
G1, S, G2
2) Prophase
3) Metaphase
4) Anaphase
5) Telophase
mitosis

4. Interphase Divided into 3 Stages: G1 Stage S Stage G2 Stage
Normal function performed
Cell growth
Organelles created (replicated)
S Stage
Chromatin (DNA strands) duplicated
G2 Stage

5. Prophase 1st Mitosis Stage
Chromatin (DNA strands) coils into chromosomes
Nucleus dissolves spilling the chromosomes
Spindle fibers form

6. Metaphase 2nd stage of mitosis
Spindle fibers attach to centromeres of each chromosome
Spindle fibers pull the chromosomes to the cell’s equator

7. Anaphase 3rd stage of mitosis
Spindle fibers pull apart the chromosomes
1 chromatid pulled to each direction

8. Telophase 4th stage of mitosis Spindle fibers dissolve
Start (interphase)
Telophase
4th stage of mitosis
Spindle fibers dissolve
Chromatids unwind into chromatin
Nucleus begins to reform
After telophase
Cytokinesis occurs (division of cytoplasm)
End result: 2 identical diploid cells
End (Telophase)

11. Name that Stage! Metaphase Hint:
Chromosomes are aligned in middle of cell

12. Name that Stage!
Telophase
Hint:
Cell plate is splitting the cell

13. Name that Stage! Interphase Hint:
Two normal looking nuclei of two cells

14. Name that Stage! Prophase Hint:
Chromosomes are forming and the nucleus is gone

Anaphase
Hint:
Chromatids are being pulled apart
