Mitosis
Bayani Gaba-gaba
You began as one cell, and now you are made of trillions, all carrying the same genetic information. The process that copies a cell exactly, again and again, is mitosis. It is how you grow, how wounds heal, how worn-out cells are replaced, and how many organisms reproduce without a partner.
In this Extended lesson you will describe mitosis as nuclear division giving identical cells, state its roles in growth, repair, replacement and asexual reproduction, explain why chromosomes are copied first, and meet stem cells, the unspecialised cells that divide to produce all the specialised cells of the body.
Manufura
- [Supplement] Describe mitosis as nuclear division giving rise to genetically identical cells (details of the stages of mitosis are not required)
- [Supplement] State the role of mitosis in growth, repair of damaged tissues, replacement of cells and asexual reproduction
- [Supplement] State that the exact replication of chromosomes occurs before mitosis
- [Supplement] State that during mitosis, the copies of chromosomes separate, maintaining the chromosome number in each daughter cell
- [Supplement] Describe stem cells as unspecialised cells that divide by mitosis to produce daughter cells that can become specialised for specific functions
