Study Notes
Mitosis is a type of cell division that results in two genetically identical daughter cells from a single parent cell. It plays a crucial role in growth, repair, and asexual reproduction.
- Mitosis — nuclear division resulting in genetically identical cells. Example: Skin cells dividing to replace dead cells.
- Chromosome Replication — exact copying of chromosomes before mitosis. Example: Chromosomes forming an X shape before cell division.
- Stem Cells — unspecialised cells that can divide by mitosis to become specialised. Example: Stem cells in bone marrow producing blood cells.

Typical Exam Questions
- What is mitosis? Mitosis is the process of cell division resulting in two genetically identical daughter cells.
- How does mitosis contribute to growth? Mitosis produces new cells, allowing organisms to grow.
- What role do stem cells play in the body? Stem cells divide by mitosis to produce specialised cells for various functions.
