Which type of cell division is required for growth and repair of the body,and which type is involved in the formation of gametes?
(N/A) There are two main types of cell division:
$1.$ Mitosis: This is the type of cell division that results in the formation of two daughter cells,each having the same number of chromosomes as the parent cell. It is essential for the growth and repair of body tissues.
$2.$ Meiosis: This is a type of cell division that results in the formation of four daughter cells,each having half the number of chromosomes as the parent cell. It is specifically involved in the formation of gametes (sex cells) for sexual reproduction.
Therefore,mitosis is required for the growth and repair of the body,while meiosis is involved in the formation of gametes.
