What is the purpose of mitosis in an organism's life cycle? a. to produce new, identical body cells b. to make copies of dna c. to produce sex cells such as sperm and egg d. to release energy for use by the cells

A.to produce new, identical body cells 

Mitosis plays an important part in the organism’s life cycle.   In unicellular or single-celled organisms,  mitosis is a type of asexual reproduction, producing identical copies of a single cell.
