Vedclass · Answer

(B) Transpiration is the evaporative loss of water by plants,which occurs mainly through the stomata in the leaves.$C_3$ plants are generally less water-efficient compared to $C_4$ plants because they have a higher rate of photorespiration and require more water to fix the same amount of $CO_2$.$CAM$ (Crassulacean Acid Metabolism) plants have evolved to keep their stomata closed during the day to minimize water loss,thus having the lowest transpiration rate.$C_4$ plants have a specialized anatomy (Kranz anatomy) that allows them to fix $CO_2$ efficiently even with partially closed stomata,leading to a lower transpiration rate than $C_3$ plants.Therefore,$C_3$ plants exhibit the highest rate of transpiration among the given options.

In which of the following is the rate of transpiration highest?
