Chromatin condenses into chromosomes. | Prophase |
Chromosomes align in center of cell. | Metaphase |
Longest part of the 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.
How many chromosomes are visible at the beginning of mitosis? Eight.
How many are in each daughter cell at the end of mitosis? Eight.
The little green T shaped things on the cell are: centrioles.
What happens to the centrioles during mitosis? The centrioles divide.
3. Identify the stages of these cells.
Metaphase Telophase Prophase
4. Describe stages of mitosis according to the animation.
Prophase The chromosomes condense. The nucleus dissipates. Centrioles migrate to opposite sides of the cell. | Metaphase Spindle fibers attach to chromosomes. Chromosomes align on the metaphase plate. | Telophase The nuclear envelope reforms. The chromosomes disperse. The spindle fibers dissolve, and the cell is pinched in two by actin protein. |
5. Record data in the chart below.
6. For each organism, identify the stage of mitosis.
Yes, I know the formatting is horrible. I blame blogger.
Interphase | Prophase | Metaphase | Anaphase | Telophase | Total | |
Number of cells | 20 | 10 | 3 | 2 | 1 | 36 |
Percent of cells (calculate: number of cells divided by total cells x 100 ) | 55 | 27 | 8 | 5 | 2 | 100 % |
6. For each organism, identify the stage of mitosis.
