Question

what is the difference between osmosis and diffusion: choose one

a: diffusion uses energy, while osmosis does not
b: osmosis it movement of proteins while diffusion is movement of water
c: osmosis is a kind of diffusion that involves movement of water
d: diffusion only occurs in animal cells while osmosis only occurs in plant cells

Answer 1

Answer:

C.

Explanation:

Diffusion is the movement of substances from an environment of high concentration to one with low concentration. Osmosis is most simply defined as the diffusion of water. Both processes are passive, so they do not require energy.

Think of a perfume you spray in a room, the perfume -when in the bottle- is in an environment with high concentration of perfume, spreads in the room; a place with no concentration of perfume. Does that seem like a process that requires ATP to you? Nope. These processes don't only happen in an organism.

Hence there goes all other options except for C.
