Question

Which process moves water molecules across the membrane of a cell? A) diffusion B) endocytosis C) exocytosis D) osmosis

Answer 1

Answer:

The correct answer will be option-D.

Explanation:

Osmosis is a process which involves the solvent movement of a solvent (water molecules) across a semi-permeable membrane.

The direction of movement is from the high concentration of a solvent or low solute to low concentration of a solvent or high solute.

Since the cell membrane is semi-permeable in nature made of hydrophobic molecules, therefore osmosis allows the passage of the water molecules when placed in a solution through aquaporin channels.

Thus, option-D is the correct answer.

Answer 2

It would be D) osmosis.
