The waxy cuticle on the upper surface of leaves helps to reduce water loss through transpiration by forming a barrier that limits evaporation. It also acts as a protective layer against pests, pathogens, and harsh environmental conditions. Additionally, the cuticle can help reflect excess sunlight and reduce heat stress on the leaf surface.

Lycopods produce sporangia which are produced on the upper surface of modified leaves termed?
The sporangia in lycopods are produced on the upper surface of modified leaves called sporophylls. These sporophylls are specialized structures that bear the sporangia and are crucial in the reproductive process of lycopods.
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.
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.
What leaf cells are covered in wax?
The cuticle layer of leaf cells is covered in wax. Wax helps to protect the leaf from excess water loss and damage from environmental factors such as UV light. It also gives leaves a glossy appearance.
What is the term for the upper surface of the tongue?
The term for the upper surface of the tongue is the "dorsum of the tongue."

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
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.

Most leaves have the upper surface more green and shiny than the lower one - Why?
The glossy and green upper surface of leaves helps to reflect excess sunlight and prevent dehydration by reducing water loss through evaporation. The lower surface may be duller to maximize light absorption for photosynthesis and has pores called stomata that allow for gas exchange and water vapor release.
Difference between dicots and monocots in terms of stomata number and distribution?
In monocot leaves stomatal distribution is almost evenly on the upper and lower surface of the leaf. In herbacious dicot stomata is distributed more on the lower surface than the upper surface. Lastly in woody dicot there is not stomatal distribution on upper surface but great distribution on lower surface of leaves.
Where is the stomata in lotus and why?
Stomata in lotus are primarily located on the upper surface of the leaves. This adaptation helps to minimize water loss through transpiration by reducing exposure to sunlight and wind, which can promote evaporation. The positioning of stomata on the upper surface also allows for efficient gas exchange and absorption of carbon dioxide.
