Question 4:
Explain the necessity of mitosis for life processes.
Answer:
• For embryonic development and organism growth, mitosis ensures rapid cell multiplication.
• When our body is injured, mitosis will produce new cells to replace dead or damaged cells.
• Through mitosis, the lizard is able to grow a new tail (regeneration) if it falls off.
• Mitosis helps organisms such as hydra to produce new individuals through bud formation.
