What is the cuticle of a plant?
This glossy look of plants’ leaves is given by something that in botanical terms is called a “ cuticle .” Precisely, the cuticle is a protective outer layer composed of cutin, a wax-like substance produced by the plant which has several different roles according to researchers. Its primary function is to prevent excessive water loss.
What is the function of the waxy cuticle?

Where is waxy cuticle found?

Why do plants have waxy cuticles?
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". It is composed of cutin, a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water. In arid regions, that is very important.
Do cacti have waxy coating?
Cacti have a thick, hard-walled, succulent stem – when it rains, water is stored in the stem. The stems are photosynthetic, green, and fleshy. The inside of the stem is either spongy or hollow (depending on the cactus). A thick, waxy coating keeps the water inside the cactus from evaporating.
Why are tropical plants waxy?
Some leaves are thick and waxy so extra water can form beads and fall down to the plant's roots. The leaves of some plants and trees are adapted to catch rain as it falls and hold it. The surfaces of these leaves are designed to absorb water slowly so it is available when the plant is thirsty.
Do plants have cuticle?
Plant cuticle is the outermost layer of plants, which covers leaves, fruits, flowers, and non-woody stems of higher plants. It protects plants against drought, extreme temperatures, UV radiation, chemical attack, mechanical injuries, and pathogen/pest infection.
Do fungi have cuticles?
The cuticle is considered as the major protective barrier that fungi should overcome. During the earliest stages of infection, fungal cutinases secreted from spores landing on the plant cuticle surface release cutin monomers from the cuticle in a spatially localized manner (Köller et al., 1982; Figure 2).

Which of these plants has thick cuticle on its leaves?
Answer: The xerophytes plants have a thick waxy cuticle on the stem and on the leaves. This waxy cuticle helps to reduce water evaporation. ... To adapt to this environment the xerophytic plant leaves reduce into spines, which reduces the surface area of the leaf and also reduces the amount of transpiration.

What is the function of waxy cuticles?
Reduces Water Loss. A primary function of the leaf’s waxy cuticle is to reduce water loss through the leaves , which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall.
What is the cuticle of a leaf?
The cuticle is a multi-layer structure composed primarily of cutin, cutan, polysaccharides, lipids and waxes. On the inward-facing side of a leaf, the cuticle attaches to the epidermal plant cell walls, and on the outward-facing side, the cuticle forms a film or skin that covers the leaf surface.
Why is the cuticle important for photosynthesis?
Leaves are the primary photosynthetic organ of a plant, so the cuticle must not seal them permanently. If it did, it would disallow the gas exchange necessary for photosynthesis. This is one reason the cuticle’s adaptation of teamwork with the stomata is important. The cuticle also works with the stomata to help complete photosynthesis. After the stomata open and carbon dioxide enters the leaf, the cuticle protects the mesophyll layer, which contains the photosynthetic cells that receive and process the carbon dioxide to manufacture glucose. The cuticle is translucent, so it does not block the sun’s rays from reaching the photosynthetic cells.

Why are desert plants cooler?
Lighter-colored leaves keep plants cooler because they reflect heat instead of absorbing it like darker colors. The leaves are typically covered with small, hair-like scales called tricomes, which give plants lighter shades of green, blue, gray and white.

Why do leaves have waxy cuticles?
To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow.
What are the pores on the leaf surfaces that open and close to regulate water and gas exchange?
