In what kind of environment might you fi nd a leaf with a very thick cuticle?

You might find a leaf with a very thick cuticle in a dry environment because it holds in moisture.

Why do some leaves have thick cuticles?

However, in plants that grow in very hot or very cold conditions, the epidermis may be several layers thick to protect against excessive water loss from transpiration. A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface.

What plant can you think of that would have a thick cuticle?

For example, in the desert where rain is scarce and the sun is hot, plants have to take water loss very seriously. Cacti and other nocturnal plants, such as agave, have especially thick cuticles to help stop water loss, but they also don’t open their stomata at all during the day.

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. …

What is the type of leaf answer?

Answer: There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc.

Why does desert plants have thick cuticles?

Plants that live in the desert are more likely to have a thick cuticle. Desert plants have thick cuticles because the cuticle will help the desert plants retain water. Such substances are hydrophobic and aid in the resistance of water loss.

What is the cuticle of a leaf?

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.

How thick is the cuticle of a plant?

Cuticle thickness varies, depending on plant type and the plant parts it covers. On leaves, the cuticle is 1/10 to 14 micrometers thick. 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.

Why is the cuticle of a leaf waxy?

Explanation: The cuticle is a waxy layer on the leaf, it helps avoid loss of water. Since plants need water, it would make sense for them to try to preserve it and use it only for the them self rather than have it evaporate. What is meaning of waxy cuticle?

How does the thickness of the cuticle affect transpiration?

The thicker the cuticle layer on a leaf surface, the slower the transpiration rate. Cuticle thickness varies widely among plant species. In general, plants from hot, dry climates have thicker cuticles than plants from cool, moist climates.

What is the cuticle of a leaf made of?

Clothes the 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.
