Why is the cuticle thicker on the upper surface than on the lower surface?
The cuticle is thicker at the top because it causes the top leaves to absorb more water. More than likely a thicker top is seen in hot and dry climates.
What adaptation would be most helpful to water lilies?
chloroplasts located only on the upper surface of leaves
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
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.
Is The lower epidermis covered with cuticle?
No, the upper epidermis is covered by a cuticle.

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.
Why both the epidermis are covered by thick cuticle in nerium leaf?
A cuticle is a protective film covering the epidermis of the leaves. Both the upper and lower epidermis are protected by this cuticle in many leaves, but leaves growing in dry areas have much thicker cuticles, serving as a structural support as well as protection.
What is the waxy waterproof layer that covers the leaves and stems of most plants?
The waxy waterproof layer that cover most plant leaves and stems is called a cuticle. The cuticle is thicker on the upper half of a leaf's surface, and it is waterproof so as the internal areas of the leaf are kept secure from flooding, That's why you water plants at the roots.
What adaptations help leaves to conserve water?
a waxy cuticle on the upper epidermis stomata that can open and close to minimise transpiration small surface area to volume ratio= less diffusion= less water loss

What is Waxy layer of the leaf?
Plants need a large surface area for the up-take of carbon dioxide from the atmosphere for the process of photosynthesis. Unforunately, this increased surface area increases the volume of water lost by transpiration, so a waxy cuticle located on the surface of the leaves reduces excessive water loss. However, this prevents gases entering or leaving the leaf, so tiny holes called stomata are postitioned on the unerside of the leaf, where less evaporation takes place, but where gases can move freely also.
What is the cuticle in a leaf?
The cuticle is a waxy covering on the leaves of plants. It is produced by the upper epidermis, which is like the skin of a leaf. Its function is to protect the leaf from water loss through evaporation. Hope this helps!
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
