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.
No, the upper epidermis is covered by a 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.
The upper epidermal layer of the Ixora coccinea leaf is typically thicker and contains more stomata compared to the lower epidermal layer. The upper epidermis also tends to have more cuticle wax to prevent water loss through transpiration. Overall, both layers serve to protect the leaf and regulate gas exchange.
The upper and lower epidermis of most leaves can be distinguished by their structure and function. The upper epidermis typically has a thicker cuticle to reduce water loss and is often more transparent, allowing light to penetrate for photosynthesis. In contrast, the lower epidermis usually contains more stomata, which facilitate gas exchange, and may have more trichomes or hairs for protection. Additionally, the arrangement of cells and presence of specialized structures can vary between the two layers.

The lower surface is the oral side. The upper surface is referred to as the aboral side.
Yes. looking at a plane's wing 'end on' - the upper surface curves, while the lower surface is straight. This causes the air flowing over the upper surface to travel further than the lower surface - which creates lift.

Lower epidermis
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.
The cuticle on the upper surface of a leaf helps to reduce water loss through evaporation and protect the leaf from damage. Since the underside of the leaf is not exposed directly to sunlight and does not play a major role in gas exchange, it does not have a thick cuticle layer.
