Question

The path of water in stomatal transpiration is

• A. Mesophyll cells substomatal chambers intercellular spaces veins stomata exterior
• B. Veins mesophyll cells intercellular spaces substomatal chambers stomata exterior
• C. Mesophyll cells veins intercellular spaces substomatal chambers stomata exterior
• D. Intercellular spaces substomatal chambers veins mesophyll cells stomata Exterior

Answer 1

The correct option is B Veins mesophyll cells intercellular spaces substomatal chambers stomata exterior

Stomatal transpiration is the loss of water in the form of water vapour from the stomata of the plant. Veins bring in water to the leaves which then enters the mesophyll cells by osmosis. The pathway is as follows:
Veins $\to$ mesophyll cells $\to$ intercellular spaces $\to$ substomatal chambers $\to$ stomata $\to$ exterior
