microfilaments do not

○ anchor the cytoskeleton to membrane proteins.
○ help determine the consistency of cytoplasm.
○ distribute chromosomes to opposite ends of a dividing cell.
○ consist of the protein called actin.
○ produce cell movement, with myosin.

Explanation:

1. Recall the functions of microfilaments (composed of actin, involved in anchoring cytoskeleton to membrane proteins, determining cytoplasm consistency, and cell movement with myosin) and the role of microtubules in chromosome distribution during cell division.
2. Analyze each option:

• Anchoring cytoskeleton to membrane proteins: Microfilaments do this.
• Determining cytoplasm consistency: Microfilaments help with this.
• Distributing chromosomes: This is done by microtubules (spindle fibers), not microfilaments.
• Consisting of actin: Microfilaments are made of actin.
• Producing cell movement with myosin: Microfilaments (actin) and myosin interact for movement.

Answer:

C. distribute chromosomes to opposite ends of a dividing cell.
