Verified step by step guidance1
Identify the key concept: The movement of water across a semi-permeable membrane.
Understand the definition of osmosis: Osmosis is the process by which water molecules move from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane.
Differentiate osmosis from other transport processes: Active transport requires energy to move substances against their concentration gradient, while facilitated diffusion involves the passive movement of molecules across a membrane via specific transport proteins.
Recognize that osmosis is a passive process: It does not require energy and occurs naturally to balance solute concentrations on either side of the membrane.
Conclude that the correct term for the movement of water across a semi-permeable membrane is osmosis, as it specifically refers to the passive transport of water.
