Are stomata present in xerophytes?
Yes, xerophytes have stomata. However, they typically have adaptations to help reduce water loss through transpiration, such as sunken stomata or hairs around the stomata to create a humid microenvironment.
Why is the stomata at the top for xerophytes?
Stomata are located on the top surface of xerophyte leaves to minimize water loss by reducing exposure to direct sunlight and wind. Placing stomata on the top surface helps create a more humid microenvironment around the stomata, reducing water loss through transpiration. This adaptation is crucial for xerophytes living in dry environments with limited water availability.
What are plant adaptation that permit them to survive in a place with limited water supply?
Xerophytes are desert plants which grow in dry and hot places. They have long and deep roots for absorption of water. The stem of xerophytes contains water storage tissues. Stems of xerophytes possess caudex (swollen part of stem that stores water). The leaves are modified into spines to minimize loss of water by transpiration. Stem and leaves usually contain tomentose (plant hairs) to reduce transpiration. Plant hairs form coating called tomentum on the surface of leaves and stem. The leaves of xerophytes are covered by thick, waxy cuticle. Stomata are reduced in number and sucken below the epidermis. Stomata of xerophytes open at night.
What problems do xerophytes face?
Xerophytes, plants adapted to arid environments, face challenges such as water scarcity, excessive heat, and high levels of solar radiation. To survive, xerophytes have developed strategies like succulence, reduced leaf surface area, and deep root systems to store water and minimize water loss through transpiration. Despite these adaptations, xerophytes are still vulnerable to drought conditions and may struggle to thrive in more temperate environments.
Which plant grows in dry areas?
Cacti are well-known for growing in dry, arid areas. They have adapted to survive in these conditions by storing water in their thick stems and having spines to reduce water loss through transpiration.

What help the fish body to reduce water loss?
The scales on the fish body helps it to reduce water loss.
What is xerophyte used for?
A xerophyte is a species of plant that can survive extremely long periods without water and has adapted to environments that present such challenges. Xerophytes are important to biologists, who study the unique way xerophytes conserve water.
How are xerophytes benefited from green and fleshy stem?
by it hav to store water
Why are stems of xerophytes green and fleshy?
As we know, xerophytes are found in deserts mostly(or you can say place having scarcity of water) so there is very less water there. So they are adapted with green and fleshy stem to store water for its use.
What are the adaptations shown by xerophytes?
Xerophytes are plants which are adapted to a dry, arid habitat such as deserts or sand dunes. They have adapted to reduce water loss so as to survive these harsh conditions. Although transpiration is unavoidable, it can be reduced in several ways.Smaller leaves, almost needle-shaped, create a far smaller surface area for water to be lost from.A densely-packed spongey mesophyll layer means that the cells have less surface area exposed to the air spaces inside the leaf, and therefore less water evaporates into these air spaces.The closing of stomata means that fewer gases can escape, and some plants, such as the Tea Plant, only open their stomata at night so as to further inhibit their water loss.A thicker waxy cuticle on the outside of the leaf makes the surface more impermeable to water, so controlling evaporation from the leaf.Hairs on the surface of the leaf, and especially around the stomata, are called trichores, and these trap humid air, and prevent said air from being moved away by currents so as to keep the water vapour potential low.Some plants have rolled leaves, which also maintains the humid air around the stomata.Extensive roots maximises the uptake of water.I hope that this is of use to you.
What is the name of plants that are adapted to exreme heat?
Plants that are adapted to extreme heat are called xerophytes. These plants have developed specialized features to survive in hot and arid conditions, such as deep root systems, thick waxy coatings on leaves, and mechanisms to minimize water loss. Examples of xerophytes include cacti, succulents, and certain grasses.
How are cactus plants adapted to store water in the desert?
While cacti do store some water in the tissues of their stems, the belief that one only as to cut open a cactus to find drinking water is a myth. Not only that, many cacti have toxic substances in their tissues which would make you sorry you ever ate a cactus.
