Mitosis and Asexual Reproduction Quiz Complete each of the following statements with a word making that statement correct. 1. Growing an entire new plant from part of the original plant is called vegetative reproduction. 2. Uncontrolled mitotic cell division is called cancer. 3. An equal division of the cytoplasm and nuclear material in cell division is referred to as Mitosis. 4. The process by which a starfish grows back a missing arm is called regeneration. This process involves the restoration of lost body parts. 5. Bread mold reproduces asexually by the process of sporulation (spore productions). 6.
