Multiple Choice

Which best describes the difference between osmosis and diffusion?

Diffusion occurs only in liquids, while osmosis occurs in gases.

Osmosis can occur in any medium, while diffusion is limited to biological systems.

Osmosis requires energy input, whereas diffusion does not.

Osmosis involves the movement of water across a semipermeable membrane, while diffusion involves the movement of solutes.

Verified step by step guidance

Begin by understanding the concept of diffusion: Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. It occurs in gases, liquids, and solids, and does not require energy input.

Next, explore osmosis: Osmosis is a specific type of diffusion that involves the movement of water molecules across a semipermeable membrane. This membrane allows only certain molecules to pass through, typically water, while blocking solutes.

Identify the key difference: While diffusion can involve any type of molecule moving from high to low concentration, osmosis specifically refers to the movement of water molecules across a semipermeable membrane.

Consider the energy aspect: Both diffusion and osmosis are passive processes, meaning they do not require energy input. This distinguishes them from active transport, which does require energy.

Summarize the distinction: Osmosis is a subset of diffusion focused on water movement across membranes, whereas diffusion is a broader term that applies to the movement of solutes in various media.
