Key Points: Significance of Mitosis
- Mitosis is an equational division that produces genetically identical daughter cells, maintaining chromosome number.
- It is responsible for growth in multicellular organisms by increasing the number of cells.
- Mitosis helps in repair, regeneration, and wound healing by replacing damaged or lost cells.
- It maintains the nucleo-cytoplasmic (surface/volume) ratio, which gets disturbed during cell growth.
- Mitosis also enables asexual reproduction in unicellular organisms and continuous cell replacement (e.g., skin, blood, plant meristems).
