Here's why:
* Mitosis is responsible for the growth and repair of tissues. It produces two identical daughter cells from a single parent cell, ensuring that each cell receives a complete copy of the parent cell's genetic material (DNA). This process is essential for maintaining the integrity of the organism's body.
* Meiosis, on the other hand, is the type of cell division that occurs specifically in reproductive cells (gametes). Meiosis results in four daughter cells, each with half the number of chromosomes as the parent cell. This is crucial for sexual reproduction, ensuring that offspring inherit a combination of genetic material from both parents.
Therefore, mitosis is the fundamental process for the development and maintenance of all cells in an organism's body except the reproductive cells.
