They can pass through the semi permeable membrane
Explanation:
The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through
If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.
