Microfilaments are solid, and they are built from a double chain of actin. explain three examples of movements that involve microfilaments

There are three examples of movements that involve microfilaments The first one is the maintenance of the cell shape (tension-bearing elements). The second is the changes in cell shape, muscle contraction, cytoplasmic streaming, cell motility (pseudopodia). The third is the cell division (cleavage furrow formation).
