Answer:
- Tissue repair / replacement.
- Organismal growth.
- Asexual reproduction.
- Development (of embryos)
Step-by-step explanation:
Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.
