Detailed explanation-1: -Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-2: -Growth: Mitosis helps in the growth and development of a child into an adult. Reproduction: Single-celled eukaryotic organisms such as amoeba reproduce by mitosis.

Detailed explanation-3: -Mitosis is used for growth and repair and produces diploid cells identical to each other and the parent cell. Meiosis is used for sexual reproduction.

Detailed explanation-4: -Replacement and regeneration of new cells-Regeneration and replacement of worn-out and damaged tissues is a very important function of mitosis in living organisms. Mitosis helps in the production of identical copies of cells and thus helps in repairing the damaged tissue or replacing the worn-out cells.

Detailed explanation-5: -Why is mitosis important to organisms? Mitosis is important to multicellular organisms because it provides new cells for growth and for replacement of worn-out cells, such as skin cells. Many single-celled organisms rely on mitosis as their primary means of asexual reproduction.
