Explanation:
Just as when we grow and need more food and energy so does a cell. when a cell is growing there is more of it that can be utilized putting more stress on the DNA to code whatever it needs. The bigger the cell is the denser and thicker the cell membrane gets making it harder for materials to work its way in and out of the cell.
The daughter cells produced from Meiosis are genetically different from each other due to the process of Crossing Over in the stage of Prophase I.
In Mitosis, there is no Crossing Over involved, since it is intended to help the body in growth and repair, not in reproduction.
Genetic Variation is important for reproduction so that not all offspring look exactly like each other or so that they do not look exactly like their parents.
