- Multicellular organisms must grow through increasing their cell count
- Mitosis allows somatic(body) cells to reproduce and form clones that perform the exact same function within the body as parent cells.
Tissue Repair:
- When damaged or injured an organism can replace the lost cells via mitosis
- Structures such as skin and bones can be reconstructed with new cells as well as lost fluids such as blood can be replenished
Asexual Reproduction:
- single celled organisms reproduce via mitosis as cellular and organismal levels of organisation are the same for them- reproduction of entire organisms
- Mitosis produces identical cells so reproduction produces clonal organisms. E.g. entire colonies of bacteria are likely to be identical to each other
- Asexual reproduction only requires one parent cell.
