Vedclass · Answer

(B) Transpiration is the process of water loss from the plant surface,primarily through stomata. Most plants,especially dicots,have a significantly higher density of stomata on the lower surface (abaxial surface) compared to the upper surface (adaxial surface). Greasing the surface blocks the stomata,thereby preventing transpiration. Since the lower surface contains the majority of the stomata,greasing it will reduce the rate of water loss more significantly than greasing the upper surface. Therefore,the leaf with the lower surface greased will retain water for the longest time and dry up last.
