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: -Mitosis is a type of cell division that occurs in almost all our cells and is necessary for our bodies to grow, develop and repair. During mitosis, two identical daughter cells are produced from a single cell.

Detailed explanation-3: -One of the main actions in the tissue repair script is cell proliferation. In order to heal after injury-whether by regeneration or scarring-cells must enter and progress through the cell cycle, a tightly-regulated process that consists of two main activities: DNA replication and mitosis.

Detailed explanation-4: -Mitosis helps in the production of identical copies of cells and thus helps in repairing the damaged tissue or replacing the worn-out cells. But the degree of regeneration and replacement in multicellular organisms vary from one another.

Detailed explanation-5: -Mitosis is the type of cell division that is required for the growth and repair of the body. Meiosis is cell division that produces gametes, or sex cells for the body.
