What is the correct description of the relationship between osmosis and diffusion?
A)
Diffusion is a type of osmosis that occurs across a cell membrane.
B)
Osmosis is a type of diffusion that occurs across a cell membrane.
C)
Osmosis is a type of diffusion that requires energy on the part of the cell, whereas diffusion happens freely.
D)
Osmosis is not directly related to diffusion. Osmosis involves the movement of liquids. Diffusion involves movement of gases.



Answer :

The correct answer is option B

Diffusion can be defined as the movement of material( particles )from an area of its higher concentration gradient to an area of its lower concentration gradient.

Osmosis can be defined as the movement of solute particles from a region of its higher concentration to lower concentration across a membrane which is semipermeable.

It can be said from the definition osmosis is a kind of diffusion across semipermeable membrane.

Answer: B

Explanation: Osmosis is a type of diffusion that occurs across a cell membrane. Osmosis is the diffusion of water across a cell membrane, excluding large solutes.
