Here's a breakdown:
* Mitosis: The process where a single cell divides into two identical daughter cells. This involves the duplication and separation of chromosomes.
* Cytokinesis: The process of physically dividing the cytoplasm and cell membrane to form two separate cells. This happens after the nucleus has divided in mitosis and is often referred to as "cleavage."
Therefore, cleavage is a part of cytokinesis, not mitosis.
