Such thick cuticle typically occurs only on plants of very dry habitats (where it is advantageous in keeping water from evaporating from the plant) or of extremely wet ones (where it prevents the abundant rainwater from leaching nutrients out of the protoplasts).
What is meant by thick cuticle?
Due to high temperature, the water is lost from the stomata of the plant as a result of the high rate of transpiration. In order to tackle the high rate of transpiration, the leaves have a thick waxy coating known as the cuticle.
What plant has a thick cuticle?
In hot climates, plants such as cacti have succulent leaves that help to conserve water. Many aquatic plants have leaves with wide lamina that can float on the surface of the water; a thick waxy cuticle on the leaf surface that repels water.
Is Xerophytes have thick cuticle?
Most xerophytic plants have a thick waxy cuticle on their stems, and leaves if they have them. The waxy cuticle also helps prevent evaporation of water by being shiny, and the shininess helps reflect the sunlight, which reduces evaporation as sunlight can cause water to evaporate.
Why is my waxy cuticle thick?
Thick, waxy cuticle – having leaves covered by a thickened cuticle prevents water loss from the leaf surface. Stomata in pits – having stomata in pits, surrounded by hairs, traps water vapour and hence reduces transpiration.

Why do sun leaves have thick cuticles?
Sun leaves become thicker than shade leaves because they have a thicker cuticle and longer palisade cells, and sometimes several layers of palisade cells. ... Transpiration rates will, of course, be higher where leaves are exposed directly to the sun. Shoots grow more quickly in height where light levels are low.
Why do desert plants have thick cuticles?
Answer: In desert plants epidermis is present as a thick waxy coating of cuticle because rate if evaporation is high in desert the thick layer prevent the water from evaporating from the plant. Thus, desert plant are able to survive in high temperature.
What are the benefits of Xerophytes on Earth on animals and on plants?
Forming water vapour-rich environment
Some xerophytes have tiny hairs on their surfaces to provide a wind break and reduce air flow, thereby reducing the rate of evaporation. When a plant surface is covered with tiny hairs, it is called tomentose.
Why are most green leaves thin and broad?
Due to their broad surface areas, green leaves can absorb more sunlight at a given time, and due to the thinness of the leaves, the light energy can easily penetrate the leaf surface and be trapped by the chloroplasts. This makes photosynthesis efficient. Therefore, green leaves are thin and broad.
Which planet has sunken stomata?
An example of xerophyte is the Cactus plant. Hence, this is the correct option. Thus, the correct answer is option (D) Xerophytes. Note:Sunken stomata is an adaptation used by Xerophytes to sustain in extremely harsh and dry conditions.
What will happen when cuticle of plant cell will be thick?
✒A common perception is that a thick cuticle is associated with a lower water permeability and thus increased tolerance to water stress.
Are hangnails skin or nail?
A hangnail only refers to the skin along the sides of the nail, not the nail itself. Hangnails are common. Most people experience hangnails when their skin is dry, such as in the winter or after being exposed to water for a prolonged period. A hangnail can become infected if exposed to bacteria or fungus.
Does desert plants have thick cuticle?
Desert plants have thick cuticles because the cuticle will help the desert plants retain water. Deserts are biomes that are dry and arid.
What is the role of cuticle?
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 the purpose of the cuticle?
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.
Is cuticle present in Roots?
The outside of the epidermis is often covered with a waxy thick layer called the cuticle which prevents the loss of water because of the deposition of a waxy substance called cutin on the outer walls of cells. Cuticles are absent in roots and hydrophytes.
Why Most leaves are flat and broad?
Leaves have flat and broad surface so that they can be more exposed towards sunlight which results in more photosynthesis.
Why some leaves are very broad?
The leaves are broad to maximize surface area for light harvest and they are thin since light cannot penetrate too deeply into the leaf (the amount of light decreases exponentially with distance).
Why is your leaf flat and thin?
The leaves are thin and flat so that they can be more exposed towards sunlight for absorption of light and carbon dioxide. This results in increased photosynthesis. ... The veins also provides larger surface area to distribute the pressure applied on leaves thereby helps in locating nutrients to tissues during an injury.
Are pineapples Xerophytes?
The pineapple is a perennial, monocotyledonous, xerophytic plant, up to 1.5 m high, of herbaceous, lily-like habit, but with tough, spiny-tipped leaves that are waxy on the upper surface and possess a fragile dusty bloom on the underside.
Which plants have leathery leaves with a thick cuticle?
Sclerophyll leaves are thick, hard and leathery, due to the presence of a waxy cuticle. This helps plants such as Eucalyptus to survive because it helps reflect sunlight, limiting water loss as the stomates remain closed for longer.
Which plants have spines instead of leaves?
cactus have spines instead of leaves to prevent a loss of water from the surface of the leaf. Cactus has spines rather than leaves so as to save water.
Why do desert plants have thick barks deep roots and thorns?
Desert plants have leaves that have evolved into spines, which help minimize water loss by evaporation and screen the plant from the sun. Their thorny spines also help protect them from predators.
What material is water proof in desert plants?
Cuticle is a water proof layer of a waxy substance called cutin which is secreted by epidermal cells. Cuticle possesses variable thickness in plants, for instance it is more thicker in xerophytic plants (or desert plants). PLZ MARK IT THE BRAINLIEST ANSWER!!!
Which plant has waxy coating on leaves?
The wax plant has thick, waxy leaves that are sometimes variegated. Peperomias are small plants with thick, waxy leaves, and may vary greatly in leaf size and shape with an upright to mounding habit. The popular jade plant (Crassula spp.) produces thick, succulent, waxy leaves; some variegated varieties are available.
