Question

Quizplus · Accepted Answer

Actin filaments form a contractile ring that wraps around the cell membrane and contracts like a purse string, causing the cell to pinch in two during cell division. Microtubules form the spindle fibers that help separate the chromosomes, intermediate filaments provide mechanical support, centrioles help organize the spindle fibers, and pili are not involved in cell division.
