Question

My textbook says that the upper part of the leaf is ventral but my teacher says that the down part is ventral.... Which is correct? Which part of the leaf transpires more?

Answer 1

Answer:

down part is correct

please mark as brainliest

Answer 2

Answer:

lower part

Explanation: All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. However, the lower epidermis (the underside of the leaf) has more, because it is more often in the shade and so it is cooler, which means evaporation won't take place as much.

hope it helps ☺️
