Learning Target: I will be able to identify and explain the stages of the Cell Cycle and Mitosis

2. Know:
Are the cells in a human baby the same as a human adult? Explain your answer.

3. Cell Division Review ?s Information Cell Cycle
The regular sequence of growth and division of cells

4. Cell Division Review ?s Information 3 Stages of Cell Cycle
Stage 1: Interphase--cell grows to mature size, copies DNA, prepares to divide into 2 cells A. Growth: cell doubles/produces all parts. B. DNA Replicated (copied)– each cell must have a complete set of DNA to survive.

5. Cell Division Review ?s Information DNA
Holds all the info a cell needs in order to do its job.
C. Prepares to divide– cell produces parts needed to divide
Stage 2: Mitosis– Nucleus divides into 2 parts– each part gets DNA

6. Cell Division Review ?s Information 4 Phases of Mitosis
(P-MAT)
1. Prophase: Chromatin condenses to make chromosomes
2. Metaphase: Chromosomes line up
3. Anaphase: Centromeres split
4. Telophase: New nuclear membrane forms around each chromosome
Prophase
Metaphase
Telophase
Anaphase

7. Cell Division Review ?s Information
Stage 3: Cytokineses: cell pinches into 2 identical daughter cells
The length of each stage varies depending on type of cell and species cell belongs to.
How long does cell cycle take?

8. Summary and Evidence
Evidence: Draw the Cell Cycle using the diagram on pages in your textbook.
