Detailed explanation-1: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.

Detailed explanation-2: -Mitosis creates identical copies of cells. For example, it creates new skin cells to replace dead skin cells. Gametes are the cells needed for reproduction. Unlike other cells, they are not produced through mitosis.

Detailed explanation-3: -When one cell divides into two, both must have a copy of the genetic information. Therefore, before cell division occurs, the genes must also make duplicates of themselves so that all of the important genetic information ends up in each of the new cells.

Detailed explanation-4: -Mitosis is the process where two identical daughter cells are formed from a single cell by the division of cells. The major purpose for cell division in mitosis is for the growth and for replacing the worn-out cells.

Detailed explanation-5: -Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.
