Question

Quizplus · Accepted Answer

Flatworms do not have specialized respiratory or circulatory systems, so oxygen reaches their cells through the process of diffusion, which involves the movement of molecules from an area of higher concentration to an area of lower concentration. The flat shape and thin body wall of flatworms allows for efficient diffusion of oxygen and other nutrients across the cell membrane.
