The document describes the stages of the cell cycle: interphase where the cell grows and matures, prophase where the nuclear membrane disappears and spindle fibers form, metaphase where chromosomes line up in the middle, anaphase where chromosome pairs split and are pulled to opposite poles, telophase where two new nuclei form and mitosis is complete, and cytokinesis where the cell divides into two daughter cells.

3. Interphase Cells matures Chromosomes in the nucleus Back

4. Prophase Nuclear membrane disappears. Spindle fibers form at the poles of the cell. Back

5. Metaphase Chromosomes line up at the middle Spindle fibers attach to each chromosome pairs. Back

6. Anaphase Chromosome pairs split and the fiber strands pull them to each pole. Back

7. Telophase Two new nuclei form at the poles of the cell where chromosomes have gathered. Mitosis is complete. Cell membrane pitches in. Back

8. Cytokinesis Two new daughter cells are formed. Back
