How does vaseline on the lower surfaces of the leaves affect them?
A leaf covered with vaseline on the lower surface wont have any affect as the stomata are being covered with the vaseline but if it were on the upper surface it would shrivel because When a leaf is loosing a lot of water vapor , it exposes the least amount of surface area to evaporation so it shrivels.
Why are there more stoma on the undersides of leaves than the top?
The upper surface of the leaf is (generally) covered by a waxy layer called the cuticle, this is not a living layer, making it particularly hard for stoma to operate on the upper surface. Additionally, the upper surface of the leaf is more exposed (direct sunlight and wind) meaning that rate of evaporation would be increased. Interestingly enough some species of plants when propagated in tissue culture do actually form stoma on the upper surface of the leaf, as there is no cuticle present.
Lycopods produce sporangia which are produced on the upper surface of modified leaves termed?
sporophylls
Why is stomata not on the top of the leaf?
Potomageton natans is an aquatic plant and its leaves are floating on water. The upper surface of leaf being away from water has stomata for gaseous exchange from air, the lower surface remains in contact with water, therefore, stomata are present on the upper surface of these leaves.
Why are the photosynthetic cells mainly on the upper side of a leaf?
The upper part of the leaf is were the most sunlight hits the leaf, so due to adaptations, chloroplasts moved to the upper parts of leaves.
What adaptation would be most helpful to water lilies?
chloroplasts located only on the upper surface of leaves
Most leaves have the upper surface more green and shiny than the lower one - Why?
The leaves are more green on the upper surface because of the presence of a large number of chloroplasts.

Why do lotus and water lily have stomata on the upper surface of the leaf?
The stomata have to be able to access air easily as its purpose is to take in and give out carbon dioxide oxygen. Since both the water lily and lotus are water plants partially submerged in water, air would be more easily accesible from the upper surface.
Stomata are found on upper or lower surface in lotus leaf?
Stomata in lotus plant is on the upper side of the leaves . BY:Alvir Tuazon
