NEET BIOLOGY

Detailed explanation-1: -Diffusion is the passive movement of molecules or particles from an area of higher concentration to an area of lower concentration. The concentration gradient incites them to diffuse.

Detailed explanation-2: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

Detailed explanation-3: -Passive transport does not require energy input. An example of passive transport is diffusion, the movement of molecules from an area of high concentration to an area of low concentration. Carrier proteins and channel proteins are involved in facilitated diffusion.

Detailed explanation-4: -Diffusion. During diffusion, substances move from an area of high concentration to an area of low concentration, until the concentration becomes equal throughout a space.
