The cuticle is well known for its functions as a
diffusion barrier limiting water and solute transport across the apoplast
and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack (Riederer, 2006).
What is the function of cuticle in epidermis?
The plant cuticle is an extracellular hydrophobic layer that covers the aerial epidermis of all land plants,
providing protection against desiccation and external environmental stresses
.
What is cuticle and write its function?
In some higher plants, the cuticle is
a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss
. … It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
What is the cuticle and what is its function in the leaf?
Introduction. 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
.
What is the function of stomata and cuticle?
Stomata on the leaf underside
allow gas exchange
. A waxy cuticle covers all aerial surfaces of land plants to minimize water loss.
Which of the following is the main function of cuticle?
The cuticle is well known for its functions as a
diffusion barrier limiting water and solute transport across the apoplast
and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack (Riederer, 2006).

What is the function of ground tissue?
Ground tissue carries out different functions based on the cell type and location in the plant, and includes parenchyma (
photosynthesis in the leaves, and storage in the roots
), collenchyma (shoot support in areas of active growth), and schlerenchyma (shoot support in areas where growth has ceased)is the site of …
What is the difference between stomata and cuticle?
*It occurs through minute pores called stomata present in epidermis of young stem and leaves. *Loss of water through stomata is called stomatal transpiration. … *Cuticle is a thin or thick layer on the epidermis of leaves and herbaceous stem. *
Cuticle reduces the use of water
, but it is not strictly imprevious to water.
What is the main function of chlorophyll?
Chlorophyll’s job in a plant is
to absorb light—usually sunlight
. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
What is Lenticels function?
– Lenticels
facilitate the gas exchange of oxygen, carbon dioxide, and water vapor in plant bodies that produce secondary growth
. – During primary growth prior to the production of the first periderm, lenticel formation typically begins beneath stomatal complexes.
Why is the cuticle waterproof?
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. … The cuticle helps seal in the water, making the leaves virtually waterproof.
What are the functions of cuticle Class 9?
The primary function of the cuticle acts as
a permeability barrier in plants to prevent the evaporation of the water from the outer epidermal surface
. Along with this, it prevents the entering of the water molecules and the solutes from the external environment.
What is cuticle Class 9?
Answer: Cuticle is
a waxy, protective layer that covers the epidermal layer of the leaves
. Cutin is waxy substance that makes up the cuticle. Explanation: In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss.
What is the main function of cuticle in plants Brainly?
cuticle is a waxy layer produced by epidermal cells. It is found on the upper epidermis of the leaf. It’s function is
to prevent excessive loss of water through the leaf surface
.
What is the meaning of cuticle skin?
The cuticle is
a layer of clear skin located along the
bottom edge of your finger or toe. This area is known as the nail bed. The cuticle function is to protect new nails from bacteria when they grow out from the nail root. The area around the cuticle is delicate. It can get dry, damaged, and infected.
