What role do actin microfilaments play in a cell?
Understand the Problem
The question is asking about the function of actin microfilaments within a cell and provides multiple choice options for possible roles. The focus is on understanding the biological significance of actin microfilaments.
Answer
Actin microfilaments support cell shape, promote movement, and aid in cell division.
Actin microfilaments provide mechanical support, determine cell shape, and enable cell movement. They are involved in processes like migration, division, endocytosis, and contractility by working with proteins like myosin.
