Question

What is the function of the waxy, transparent top layer of leaves?

Answer 1

Hint: The cuticles, top epidermis, palisade layer, and spongy layer are all crucial structures that are required for the plant's survival. As a result, photosynthesis is primarily responsible for the palisade layer creating food and oxygen for the plant. The mesophyll is the region that contains the palisade and spongy layers.

Complete answer:
The waxy, translucent top covering of the leaves keeps microbes out while also preventing excessive water loss from the plant body.
The waxy layer on the epidermis of leaves that slows transpiration is known as the cuticle. It's primarily found in desert plants because it reduces water loss.

Cuticle refers to the waxy, translucent upper layer of leaves. It's a non-cellular protective layer present on the outside of many plants' epidermis. The cuticle serves as a water permeability barrier, preventing excessive water loss from the plant's body due to evaporation. It also protects plant tissues by keeping germs and outside water from entering.

Leaves have an outer layer that protects them, just like human skin does. The cuticle is the outermost layer of the skin. It's usually waxy to preserve the leaf and keep water from escaping. When you touch a leaf, you may notice a waxy coating, and on some plants, such as holly, the waxy coat may even shine a little.

The epidermis is the layer of skin beneath the cuticle. The upper epidermis is located at the top of the leaf. A single layer of cells can be discovered directly beneath the cuticle. It protects the leaf by reducing water loss and creating an additional layer between the leaf's exterior and inside surfaces.

Note:-
Stomata are tiny pores on the surface of the leaf that regulate gas exchange during photosynthesis. However, the lower epidermis (the underside of the leaf) has more because it is more typically in the shadow and hence cooler, allowing for less evaporation. It's crucial to understand that leaves are produced by primary growth and originate at the apical meristem.
