Why are leaves reduced to spine?
Explanation: leaves of some plants are reduced to spines In order to prevent water loss and reduce rate of transpiration. this kind of plant grows in desert areas where dry conditions are dominant.
Why are leaves reduced to spines in desert plants?
Leaves of desert plants are reduced to spines to prevent transpiration.
What is the advantage of leaves reduced to spines in some Xerophytes?
Spines lose less water than leaves so are very efficient in a hot climate. Spines also prevent animals from eating the plant. Waxy skin – some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration .
How does the rate of loss of water gets reduced in desert plants?
Answer : Cuticle is a protective waxy covering produced by epidermal cells of leaves and other plant parts. In desert plants, cuticle reduces the rate of water loss through transpiration and helps in conserving water as there is always a shortage of water for desert plants.
Are leaves reduced to spines in Xerophytic plants?
➡️✨✨In case of cactus or xerophytic plants, leaves are redued to spines to prevent loss of water through transpiration and stem performs the process of photosynthesis.
What happens in plants with reduced leaves like the desert plants?
The leaves of the desert plants are reduced to spines to help to prevent the loss of water by transpiration. Transpiration is the process by which plants give out excess water in the form of vapour from their aerial parts.
What are the advantages of leaves?
These leaf particles add valuable nutrients right back into the soil, resulting in a stronger, healthier lawn. Insulation. A thin layer of mulched leaves can help protect your lawn from harsh winter conditions, ensuring a healthy lawn next spring.
How does the presence of spines instead of leaves in desert plants useful?
In cacti, spines are wholly transformed leaves that protect the plant from herbivores, radiate heat from the stem during the day, and collect and drip condensed water vapour during the cooler night. In the many species of the spurge family…
Which plant has spines instead of leaves and grows in desert?
Answer: Cactus grows in desert environment, where there is scarcity of water. The leaves of cactus are modified into spines, to prevent water loss from the surface of leaves. Thus, the stem is the centre of photosynthesis in the cactus plants instead of the leaves.
How does stomata is being protected from water loss?
To protect itself against water loss the leaf has a waxy cuticle blocking water loss but it still need these openings to exchange Oxygen and Carbon Dioxide with the environment that it needs for photosynthesis. To do this the leaf has specialized epidermal cells that surround the stoma called guard cells.
What is the normal route of water loss in terrestrial plants?
Evapotranspiration is the normal route of water loss in terrestrial plants.
Why do Xerophytes have sunken stomata?
Answer: sunken stomata are present in xerophytic so as to reduce the water loss from the plants because xerophytic plants are dessert plants and they already have less amount of water in them . That’s why they have to store the water and for this the stomata s are sunken in them…..
