The movement of water across a membrane from an area of higher water concentration to an area of lower water concentration is known as
A) osmosis.
B) active transport.
C) diffusion.
D) facilitated diffusion.
E) filtration.

Question

Quizplus · Accepted Answer

This describes the process of osmosis, where water moves down its concentration gradient to equalize the concentration on both sides of the membrane. Active transport involves movement against the concentration gradient, diffusion and facilitated diffusion refer to movement of molecules other than water, and filtration involves the movement of solutes through a membrane under pressure.
