Detailed explanation-1: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.
Detailed explanation-2: -Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.
Detailed explanation-3: -Final answer: Movement of molecules from their higher concentration to their lower concentration is called diffusion.
Detailed explanation-4: -In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.
