A cleavage furrow is a structure that forms during the final stages of cell division, specifically in a process called cytokinesis. It appears as a shallow groove in the cell's surface, indicating where the cell will split into two daughter cells. This furrow is created by a ring of proteins that contract, pulling the cell membrane inward.
As the cleavage furrow deepens, it eventually pinches the cell in two, allowing each new cell to have its own nucleus and cytoplasm. This process is crucial for growth and repair in multicellular organisms, ensuring that each daughter cell receives the necessary components to function properly.
