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.

What does the waxy layer do in a plant cell?
Transparent waxy cuticle – a protective layer that allows light to enter the leaf. It is waterproof in order to prevent water loss by evaporation.
What is the waxy layer in roots called?
The roots of all plants have a layer of wax called suberin. This waxy layer surrounds large parts of the inside of the root, known as the vascular bundle, which is responsible for the transport of water and nutrients from the soil to the leaves.
Where is the waxy layer on a leaf?
The epidermis secretes a waxy substance that coats the outside of the leaf, the cuticle.
Why would a plant have thick waxy leaves?
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". ... The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.
Why upper layer of leaf is waxy?
The epidermis secretes a waxy cuticle of suberin, which restricts evaporation of water from the leaf tissue. This layer may be thicker in the upper epidermis compared to the lower, and in dry climates compared to wet ones.
What is waxy substance?
wax, any of a class of pliable substances of animal, plant, mineral, or synthetic origin that differ from fats in being less greasy, harder, and more brittle and in containing principally compounds of high molecular weight (e.g., fatty acids, alcohols, and saturated hydrocarbons).
Is Cutin and cuticle same?
Cutin and waxes are fatty substances deposited in the walls of epidermal cells, forming a waterproof outer layer called the cuticle. ... Cutin is the major component of the cuticle, the waxy, water-repelling surface layer of cell walls exposed to the environment aboveground.
What does the cuticle do in 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.
Why are some leaf surface shiny?
Due to more amount of chlorophyll on the upper surface more light energy is trapped hence more amount light of green wavelength is reflected. It is shiny because the layer of cuticle is thicker on the upper surface in comparison to lower surface.
What color is the waxy layer?
The outer surface of the leaf has a thin waxy covering called the cuticle (A-yellow), this layer's primary function is to prevent water loss within the leaf. (Plants that leave entirely within water do not have a cuticle). Directly underneath the cuticle is a layer of cells called the epidermis (B-dark green).
Why are some leaves glossy?
However, the reason that the plants leaves are shinier on top is due to a protective wax call cutin that helps the plant to retain water during transpiration.
What is an example of a wax?
Wax is a sticky substance that is made from honeycomb or any substance with a similar feel. An example of wax is the substance produced by a burning candle. An example of wax is what you clean out of your ears with a cotton swab.
Which part of plants contain waxy cell wall?
The plant cuticle is a layer of lipid polymers impregnated with waxes that is present on the outer surfaces of the primary organs of all vascular land plants.
