Question

1. which type: of passive transport refers to the movement of only water molecules across a membrane?

facilitated diffusion
osmosis
diffusion
active transport

Explanation:

• Facilitated diffusion: Moves solutes via membrane proteins, not only water.
• Osmosis: Defined as the passive movement of only water across a semipermeable membrane.
• Diffusion: Moves any solute or substance down its gradient, not only water.
• Active transport: Requires energy, so it is not passive transport.

Answer:

osmosis
