Study Notes
Purpose of Mitosis
- Mitosis allows existing cells to produce new, genetically identical cells.
- Essential for growth and development in organisms, contributing to the overall increase in size through new cell creation.
- Facilitates the replacement of dead or damaged cells to maintain tissue integrity.
Reasons for Cell Division
- Growth and development of organisms necessitates cell division through mitosis for increasing cell numbers.
- Replacement of dead or dying cells is crucial for sustaining bodily functions and health.
Apoptosis
- Refers to programmed cell death, which is a natural process allowing the body to eliminate damaged or potentially cancerous cells.
- Particularly important in areas where cells may accumulate significant genetic mutations over time.
Somatic Cells and Division
- Brain cells and heart muscle cells are examples of somatic cells that generally do not undergo mitosis.
- These cells are specialized and have limited capacity for regeneration, impacting recovery from injury.
Rapid Cell Division Locations
- The highest rates of cell division occur in the blood cells and cells lining various tissues and organs.
- These regions are critical for maintaining health and responding to damage or loss.
