What function of cuticle on the upper surface of the fern leaves?

Does moss have cuticle?
Yes, moss does have a cuticle. The cuticle in mosses is a waxy layer covering the upper surface of the leaves, helping to prevent water loss and protect against environmental stresses.
Why is the cuticle thicker on the upper surface than on the lower surface?
The thicker cuticle on the upper surface of leaves helps to reduce water loss through transpiration and protect the leaf from environmental stresses like sunlight, wind, and pathogens. This adaptation helps the plant retain moisture and function more efficiently in photosynthesis and gas exchange.

Why is the upper surface of many leaves is covered in a waxy cutiicle?
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.
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

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.
Is The lower epidermis covered with cuticle?
No, the upper epidermis is covered by a cuticle.
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.
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.
