Class 11 Biology - Chapter Cell cycle and Cell Division NCERT Solutions | Why is mitosis called equational divisio
Welcome to the NCERT Solutions for Class 11th Biology - Chapter Cell cycle and Cell Division. This page offers a step-by-step solution to the specific question from Excercise 1 , Question 5: why is mitosis called equational division....
Question 5
Why is mitosis called equational division?
Answer
Mitosis is the process of cell division wherein the chromosomes replicate and get equally distributed into two daughter cells. The chromosome number in each daughter cell is equal to that in the parent cell, i.e., diploid. Hence, mitosis is known as equational division.
