Which describes the passive process by which molecules of a solute move through a cell membrane from an area of higher concentration to an area of lower concentration?
A) Osmosis
B) Filtration
C) Hydrostatic pressure
D) Diffusion

Question

Quizplus · Accepted Answer

Diffusion is the passive process by which molecules move from an area of higher concentration to an area of lower concentration, due to the random movements of molecules. This is a fundamental mechanism for the transport of molecules across cell membranes without the input of energy or an external force. Osmosis is a specific type of diffusion where water molecules move across a membrane to equalize concentration, whereas filtration and hydrostatic pressure involve the movement of fluids across a membrane due to pressure differences.
