Question

Quizplus · Accepted Answer

This is the definition of diffusion, which is the passive movement of molecules from a high concentration to a lower concentration down a concentration gradient. Facilitated diffusion and active transport both require the use of proteins to move molecules, whereas osmosis specifically refers to the movement of water molecules. Endocytosis is a cellular process in which cells engulf external materials.
