What would happen to an organism if mitosis did not occur? Check all that apply.
vitfil [10]

The correct options are:

The organism would not grow.

If an organism were cut or burned, the damaged area would not heal.

The organism would not produce new cells.

The mitosis is essential for the division of the cells. The division of the cells allow the organism to grow and heal the damaged cells. The division of the cells replace the old cells and multiply the number of the cells in an organism. hence, in any condition, the organism would be affected and in the absence of the mitosis, the organism cannot heal and cannot grow, due to non-production of new cells.
