Photosynthesis
Mitosis
Learning Outcomes:
1. Describe the steps involved in Mitosis 2. Explain the purpose of Mitosis |
|
What can affect mitosis and the speed it occurs at?
The following can slow down mitosis: temperature, pH, presence of mutagens such as alcohol or radiation, availability of raw materials in the cell.
Mitosis is usually higher during periods of growth and repair during infancy / childhood / early development in animals following the breaking of dormancy, and during seasonal growth in plants following damage to the organism when repair of tissue is necessary.
Mitosis occurs at a higher rate in areas where most growth or replacement of cells is occurring, such as:
· root / shoot tips
· hair follicles
· bone marrow
· skin cells
· mucous membranes etc.
Mitosis rates increase in areas of cellular repair, the site of damage. Mitosis rates increase in Cancer cells.
