Multiple Choice
How is osmosis related to diffusion in terms of movement across a membrane?
A
Osmosis is a type of diffusion that involves the movement of water across a selectively permeable membrane.
B
Osmosis requires energy input, whereas diffusion does not.
C
Osmosis is the movement of solutes across a membrane, while diffusion involves only gases.
D
Osmosis and diffusion are unrelated processes that occur in different environments.
Verified step by step guidance
1
Understand that both osmosis and diffusion are processes that involve the movement of particles from an area of higher concentration to an area of lower concentration, but they differ in the type of particles they involve.
Recognize that diffusion is a general process where molecules spread out evenly in a space, and it can involve gases, liquids, or solids moving down their concentration gradient without the need for a membrane.
Identify that osmosis is a specific type of diffusion that involves the movement of water molecules across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Clarify that osmosis does not require energy input, as it is a passive process driven by the concentration gradient of water, similar to diffusion.
Differentiate between the two by noting that osmosis specifically involves water and a membrane, whereas diffusion can involve any type of molecule and does not necessarily require a membrane.
