Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
- This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.
Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
- This is because meiosis occurs in gametes and is used in reproduction.
Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
- This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.
