Understanding the Cytoskeleton and Cleavage Furrow

The cleavage furrow is a structure that forms during cytokinesis, the process by which a cell divides to form two daughter cells. It is crucial for the physical separation of cells.

Identifying the Relevant Aspect

1. Microtubules: These are part of the cytoskeleton and play a role in cell shape and transport but are not primarily involved in forming the cleavage furrow.

2. Intermediate Filaments: These filaments provide structural support to cells and are not directly involved in the cleavage process.

3. Actin Filaments: These are crucial for cell movement and shape changes. They play the primary role in forming the cleavage furrow as they contract and pinch the cell membrane.

4. Centrioles: While centrioles are involved in organizing microtubules during cell division, they do not directly contribute to the cleavage furrow formation.

5. Spindle Fibers: These are made of microtubules and are involved in separating chromosomes but not in the actual furrow formation.

Conclusion

The correct answer to the question about which aspect of the cytoskeleton is involved in the cleavage furrow is actin filaments.
