Solution
The correct option is C Diffusion
- Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. During transpiration, water is lost in gaseous or vapour form from the leaves, where it is present at a higher concentration as compared to the atmosphere, where water vapours are present in a lower concentration. This phenomenon also explains the condition that when the humidity is high, the transpirational loss of water is less due to the difference in concentration of water between the leaves and the atmosphere.
Thus, the correct answer is option C.
