Which of the following is true about osmosis?
A) Water may move up or down a concentration gradient during osmosis.
B) Osmosis is the flow of water across a plasma membrane.
C) Osmosis occurs when the concentration of water is the same as the concentration of solutes.
D) Solutes always accompany the movement of water during osmosis.

Question

Quizplus · Accepted Answer

Osmosis specifically refers to the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, aiming to equalize solute concentrations on both sides of the membrane. It does not require solutes to move with the water, nor does it occur when water and solute concentrations are equal. Water moves down its concentration gradient (from higher water concentration to lower), not up.
