1. At which stages do these occur?
Chromatin condenses into chromosomes: prophase.
Chromosomes align in center of cell: metaphase.
Longest part of cell cycle: interphase.
Nuclear envelope breaks down: prometaphase.
Cell is cleaved into two new daughter cells: cytokinesis.
Daughter chromosomes arrive at the poles: telophase.
2. Watch the video and answer these questions:
How many chromosomes are visible at the beginning of mitosis? 0.
How many are in each daughter cell at the end of mitosis? 4.
The little green t-shaped things on the cell are: daughter chromosomes.
What happens to the centrioles during mitosis: they divide.
3. Identify the stages of these cells:
1. Metaphase.
2. Telophase.
3. Prophase.
4. Describe the cell in the following stages:
1. Prophase: Daughter chromosomes seem to be moving towards the ends.
2. Metaphase: Pulling the other chromosomes towards them.
3. Telophase: Cell begins to split into two.
