Detailed explanation-1: -Facilitated transport is a type of passive transport. Unlike simple diffusion where materials pass through a membrane without the help of proteins, in facilitated transport, also called facilitated diffusion, materials diffuse across the plasma membrane with the help of membrane proteins.

Detailed explanation-2: -Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.

Detailed explanation-3: -Both facilitated diffusion and simple diffusion are types of passive transport. They move substances from an area of high concentration to an area of low concentration. However, the former is different from the latter in the way molecules are transported across the membrane.

Detailed explanation-4: -In simple diffusion, the movement of particles takes place with the direction of the concentration gradient. In facilitated diffusion, the movement of molecules can take place in both ways – along the direction and opposite of the concentration gradient.

Detailed explanation-5: -1: Passive Transport: Diffusion is a type of passive transport. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm).
