उत्तर
Transpiration rate is reduced due to less surface area of leaf, bending of leaf and by sunken stomata.
Explanation:
Each of these modifications serves as an effective mechanism for plants to conserve water. A smaller leaf surface area directly reduces the total number of stomata available for evaporation, while the rolling or bending of leaves traps escaping water vapour to create a highly humid pocket of air that slows down further moisture loss. Similarly, sunken stomata are deeply recessed within pits, which protect them from direct airflow and create a localised microclimate of still, humid air that dramatically lowers the overall rate of transpiration.
