1. Essential Question: In the cell cycle, explain how interphase is different from mitosis.

2. The Cell

3. The Cell Cycle
The cell cycle includes interphase, mitosis, and cytoplasmic division, and it is highly regulated.

4. Interphase
During interphase, a cell duplicates membranes, ribosomes, organelles, and DNA
Interphase terminates when mitosis begins.
The cell spends most of its life in interphase.

5. Cell Division Meiosis is a form of cell division that forms sex cells.
Mitosis is the division and distribution of complete sets of genetic material to new cells, increasing overall cell number.
The stages of mitosis are prophase, metaphase, anaphase, and telophase.

6. Cytoplasmic Division (cytokinesis)
A process that distributes the cytoplasm into two portions and is completed at about the same time as mitosis.

7. Differentiation Differentiation is cell specialization
Stem cells provide new cells for growth and repair.
Stem cells give rise to other stem cells and to progenitor cells that begin to specialize.
Differentiation reflects the activation of specific sets of genes.

8. A cell that does not divide or differentiate may undergo apoptosis, a form of cell death that is a normal part of development.
