Answer:
No, because the stomata on the lower surface would be dipped in water which will be no use. Hence lilies have stomata on the upper surface that helps them in transpiration as well as in photosynthesis.

Answer:
Because all physiological process take place from upper surface only.
Explanation:
Stomata are present for gaseous exchanges and for 3 physiological processes :-
a) Photosynthesis
b) Respiration.
c) Transpiration
In water lily the leaves float on the surface of water. Thus lower surface is in touch with water and only upper surface is exposed. So all the three above mentioned functions are performed by stomata which are restricted to upper surface only.
