Diffusion
B
Active transport
C
Osmosis
D
Facilitated diffusion
Verified step by step guidance1
Understand the concept of diffusion: Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
Recognize the role of a semipermeable membrane: A semipermeable membrane allows certain molecules or ions to pass through it by diffusion and occasionally facilitates active transport.
Define osmosis: Osmosis is a specific type of diffusion that involves the movement of water molecules across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Differentiate osmosis from other types of transport: Unlike active transport, osmosis does not require energy input and is driven by concentration gradients.
Identify osmosis in the context of the problem: Given the options, osmosis is the correct term for the diffusion of water across a semipermeable membrane.
