Question

Which phrase best describes osmosis? A. the process by which the cytoplasm physically divides B. the process of DNA synthesis C. the process where distribution of molecules is balanced out by their movement D. the process where a selectively permeable membrane allows the movement of water through it

Answer 1

D is the correct answer because osmosis is the movement of a solvent ( mainly water ) from area of higher concentration to that of lower concentration through a semi-permeable membrane ..

Answer 2

D. the process where a selectively permeable membrane allows the movement of water through it

Step-by-step explanation:

Osmosis is the movement of water molecules through a selectively permeable membrane from the region of high water potential to the region of low water potential.

It can also be defined as the movement of water molecules through a selectively permeable membrane from the region of low solute concentration to the region of high solute concentration.

Hence, osmosis always involves the movement of water molecules through a selectively permeable membrane.

The correct option is D.
