Explanation: 

Detailed explanation-1: -Osmosis And Diffusion Definitions Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

Detailed explanation-2: -Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air.

Detailed explanation-3: -Passive transport, most commonly by diffusion, occurs along a concentration gradient from high to low concentration. No energy is necessary for this mode of transport.

Detailed explanation-4: -In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
