Means of Transport

Question

Mark the incorrect statement regarding diffusion.

Easy

A

It is a passive process.
B

It is not dependent on a ‘living system’.
C

It occurs against the concentration gradient.
D

In the absence of other forces, a substance will diffuse from where it is more concentrated to where it is less concentrated.

Solution

Diffusion takes place along the concentration gradient. Therefore, it does not require expenditure of energy to transport substances from one part of the cell to the other, or from cell to cell, or over short distances, say, from the intercellular spaces of the leaf to the outside.
