Osmosis

Detailed explanation-1: -Osmosis is a type of passive transport . No energy is required for osmosis.
Detailed explanation-2: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.
Detailed explanation-3: -Hence, facilitated diffusion is not an active transport.
Detailed explanation-4: -There are three main active transport methods-ion pumps, exocytosis and endocytosis.
Detailed explanation-5: -Osmosis does not require energy, i.e. ATP for the movement. Passive diffusion is the movement of solute from high concentration to low concentration. They do not require ATP to carry out the movement.
