Osmosis involves which of the following processes?

a. movement of water up a concentration gradient

b. movement of solute up a concentration gradient

c. movement of water across a cell membrane

d. movement of solute across the cell membrane

Osmosis involves moment of movement of water across the cell membrane to maintain the concentration gradient

Option C

Explanation:

The exchange of solute or the solvent particles across a semipermeable membrane to match up the concentration gradient takes place through different processes of which the most common is the osmosis and the diffusion.

The osmosis involves movement of solvent or water from a low concentrated solution to a high concentration solution in order to equalize the concentration gradient on both the sides, diffusion is the movement of solute molecules.
