Detailed explanation-1: -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-2: -Osmosis only occurs when a semi-permeable membrane is present, but diffusion can happen whether or not it is present. 3. Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely.

Detailed explanation-3: -Diffusion is the movement of molecules from a region of its higher concentration to a region of its lower concentration. It does not need a semi-permeable membrane to happen. A semi permeable membrane is required for the process of osmosis to happen.

Detailed explanation-4: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.
