📖 Physical Concept & Comprehensive Explanation
Mitosis powers organismal somatic growth, regeneration, and asexual reproduction. It progresses through five sequential phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. Dysregulated mitotic cycles cause uncontrolled cellular proliferation leading to oncogenic tumors.
🎯 High-Yield Revision Points
- ✓Known as equational division because ploidy is conserved (2n -> 2n).
- ✓Drives tissue growth, maintenance, and wound repair.
- ✓Unchecked mitotic proliferation triggers cancer.

Q1: Why is mitosis called equational division?
Because chromosome number and genetic composition in daughter cells remain identical to the parent cell.
