How are diffusion and osmosis different?
A
Diffusion involves the movement of solute particles, while osmosis involves the movement of solvent molecules.
B
Diffusion requires a semipermeable membrane, while osmosis does not.
C
Osmosis occurs in gases, while diffusion occurs in liquids.
D
Diffusion is a passive process, while osmosis is an active process.
Verified step by step guidance
1
Understand that diffusion and osmosis are both processes that involve the movement of particles, but they differ in the type of particles that move and the conditions under which they occur.
Recognize that diffusion involves the movement of solute particles from an area of higher concentration to an area of lower concentration, and it does not require a semipermeable membrane.
Identify that osmosis specifically refers to the movement of solvent molecules, typically water, across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Clarify that diffusion is a passive process, meaning it does not require energy input, while osmosis is also a passive process, not an active one, as it relies on the natural kinetic energy of molecules.
Note that diffusion can occur in gases, liquids, and solids, whereas osmosis is a process that occurs in liquid solutions where a semipermeable membrane is present.
