Detailed explanation-1: -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.

Detailed explanation-2: -Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Detailed explanation-3: -Diffusion is a passive process which means it does not require energy. Small particles diffuse faster than large ones. Eg substances like oxygen, carbon dioxide and glucose move in and out of cells by diffusion. The greater the difference in concentration, the faster the rate of diffusion.

Detailed explanation-4: -Answer and Explanation: The statement about diffusion that is false is 1) Simple diffusion depends upon specific carrier proteins. Diffusion is a passive process that doesn’t require carrier proteins, but relies on a difference in concentration.

Detailed explanation-5: -Faciliated transport is a type of active transport. Diffusion and Osmosis are types of Passive transport which don’t require expenditure of energy ATP.
