Multiple Choice

How does osmosis differ from diffusion in terms of the movement of molecules?

Osmosis requires energy input, while diffusion occurs spontaneously without energy.

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

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

Osmosis occurs only in living organisms, while diffusion can occur in both living and non-living systems.

Verified step by step guidance

Understand the basic definitions: Osmosis is the movement of water molecules across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, and it can involve any type of molecules, not just water.

Identify the key difference in the type of molecules involved: Osmosis specifically involves water molecules, whereas diffusion can involve any type of molecules, including solutes.

Consider the role of a semipermeable membrane: Osmosis requires a semipermeable membrane that allows only certain molecules (typically water) to pass through, while diffusion does not require such a membrane and can occur in open spaces.

Examine the energy requirements: Both osmosis and diffusion are passive processes, meaning they do not require external energy input. They rely on the natural kinetic energy of molecules.

Clarify the environments where these processes occur: Osmosis is a process that is crucial in biological systems, particularly in maintaining cell turgor and homeostasis, but it can also occur in non-living systems where a semipermeable membrane is present. Diffusion can occur in both living and non-living systems without the need for a membrane.
