- Mitosis
Prophase Chromatin condenses to form chromosomes. Centrioles migrate to opposite poles of the cells (except in plant cells which do not have centrioles). Microtubules develop and form a star shaped structure known as an aster, and spindle fibres may develop....
- The Cell Cycle
What are all of the stages to the Cell Cycle? The Cell Cycle starts with its first stage called Interphase. The cell will be in this stage the longest amount of time out of all of the stages of the cycle. During the first part of Interphase is called...
- #80 Question 3
(a) The diagrams show a cell in various stages ofthe mitotic cell cycle. Name the stage represented by each diagram, and arrange them in the correct sequence. (b) Describe the role of spindle microtubules in mitosis. (3 marks) (c) The graph below shows...

Mitosis is a nuclear division giving rise to genetically identical cells in which the chromosome number is maintained by the exact duplication of chromosome. Significance of mitosis production of geneticlly identical cells: It keeps the chromosome...

Comparison between cytokinesis in plant cell and animal cell
Cytokinesis in plant cell and animal cell: Major Differences
| Cytokinesis in plant cell | Cytokinesis in animal cell |
| 1. Mechanism of cytokinesis is cell plate. | By cell furrow. |
| 2. Spindle usually persists. | Spindle begins to degenerate. |
| 3. Golgian and ER vesicles called phragmoplasts fuse to form cell plate. | A constriction is developed by the contraction of microtubules in the cell membrane. |
| 4. Cell plate grows centrifugally. | Cell furrow grows centripetally. |
