Detailed explanation-1: -Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell.
Detailed explanation-2: -When we are adults many cells mature and become specialised for their particular job in the body. So they don’t make copies of themselves (reproduce) so often. But some cells, such as skin cells or blood cells are dividing all the time. When cells become damaged or die the body makes new cells to replace them.
Detailed explanation-3: -For the survival and growth of organisms. Maintaining chromosome numbers. Damaged cells are renewed.
Detailed explanation-4: -Food, Waste, and Gas Exchange. They need to maintain a workable ratio of surface area to volume to allow an efficient transfer of materials in and out of the cell. Growth. In order for an organism to grow, they must divide so they can get larger. Repair. Reproduction.
