Answer :
Mitosis is necessary for growth and repair in the body because it increases the number of cells by dividing but without affecting the genetic material of the cells.
Mitosis is the type of cell division. Here, a cell divided to produce two daughter cells. These cells are genetically identical to each other as well as to the parent. The genetic material in the cells remains the same even after division and this is the reason why mitosis is also referred to as equational division.
Cell is the fundamental unit that forms the building block of all organisms. It is comprised of plasma membrane, cytoplasm and various cell organelles that work together to make the cell functional.
