Movement of amoebae across a surface requires which of the following activities by components of the cytoskeleton?
A) assembly of actin filaments to form bulges in the plasma membrane
B) assembly of microtubule extensions that vesicles can follow in the direction of movement
C) reinforcement of the pseudopod with intermediate filaments
D) localized contractions driven by myosin and microtubules

Question

Quizplus · Accepted Answer

Amoebae move by extending parts of their cell in a process called pseudopodia, which involves the assembly of actin filaments at the leading edge to form bulges in the plasma membrane. This actin polymerization pushes the membrane outwards, creating the movement.
