The slight indentation that forms as a cell divides during cytokinesis is indeed called the cleavage furrow. This process occurs in both animal and fungal cells. Here's a step-by-step explanation:

1. As the cell prepares to divide, the cytoskeleton inside the cell, specifically the microtubules, begin to reorganize themselves into a structure called the spindle apparatus.

2. The chromosomes, which have already been duplicated, align along the middle of the cell. The spindle fibers attach to the chromosomes.

3. The spindle fibers then contract and pull the sister chromatids apart, moving them to opposite ends of the cell.

4. While this is happening, a cleavage furrow begins to form around the middle of the cell. This is a slight indentation caused by the cell membrane starting to pinch inwards.

5. The cleavage furrow deepens as the cell membrane continues to pinch inwards, driven by a ring of actin and myosin filaments that contract.

6. Eventually, the cleavage furrow pinches the cell into two separate cells, each with a complete set of chromosomes. This is the final step of cytokinesis.
