Question

Quizplus · Accepted Answer

Microvilli are thin folds on the surface of the plasma membrane that increase the surface area of the cell, which is important for processes like absorption and secretion. Cilia and flagella are not folds, but are hair-like structures that protrude from the surface of the cell and move in a coordinated manner. Vesicles are small sacs formed from the membrane that transport materials within the cell or to the cell membrane for secretion.
