The main difference between osmosis and diffusion is that
A) diffusion is passive transport, whereas osmosis is active transport.
B) diffusion is more efficient than osmosis over longer distances.
C) osmosis refers to the movement of materials across a semipermeable membrane, but diffusion does not involve a membrane.
D) osmosis refers specifically to the movement of water, whereas diffusion refers to the movement of any molecules.
E) the process of osmosis varies according to the kinds of particles present, but diffusion does not.

Question

Quizplus · Accepted Answer

Osmosis is a type of diffusion that specifically refers to the movement of water across a semipermeable membrane, whereas diffusion refers to the movement of any molecules from an area of high concentration to an area of low concentration. Therefore, the main difference between osmosis and diffusion is that osmosis refers to the movement of water molecules, whereas diffusion can involve the movement of any type of molecule. None of the other options accurately capture the main difference between osmosis and diffusion.
