Desert plants have adapted to minimize water loss through several mechanisms. They often possess thick, waxy cuticles that reduce transpiration, while some have specialized structures like modified leaves (e.g., spines in cacti) that decrease surface area. Many also utilize CAM (Crassulacean Acid Metabolism) photosynthesis, allowing them to open their stomata at night to take in carbon dioxide, thereby conserving water during the hotter daytime hours. Additionally, deep root systems help them access underground water sources efficiently.

Which body structure allows mammals to control body fluids and adapt to dry desert conditions?
The kidney is the body structure that allows mammals to control body fluids and adapt to dry desert conditions. The kidney filters waste products from the blood and regulates the balance of water and electrolytes in the body, helping to conserve water and prevent dehydration in desert environments.
Facts about desert plants?
Desert plants have well developed vascular tissue and root system, have latex in the body, spiny, waxy and cuticularized surface to minimize water loss by transpiration.
How can plants like cactus and acacia live in deserts with scarce water?
The plants are designed (or evolved) to store extra water in the plant body or in underground roots when there is rain or water available and the skin of the plants keeps moisture in the plant from evaporating.
What is role of cutin in desert plants?
In order to understand why desert plants have cuticles (cutin) you first have to know what cutin is, it's function, and why some plants have it. Then you can begin to answer why plants specialized for desert climate have cutin. Cutin is a fatty, wax-like substance secreted by a plant's dermal tissue system. The dermal tissue is also known as the epidermis which is the outermost layer of cells on all young plant organs. If you consider all of this "waxy stuff" as a whole it is termed "cuticle,"similar to the cuticle above your nails. As you can imagine, wax is insoluble in water and therefore "water-proofs" the skin of the plant. In other words, it dictates how much water is lost through the epidermal cells by evaporation, ensures water does not enter, and also keeps other molecules from entering. The cuticle also protects again UV radiation. Regarding plant's evolutionary history, the adaptation of cutin provided a way for marine plant life to move onto land. Suppose if you were a marine plant and your entire body was surrounded in water, you would rely less on gaseous exchange and evolving structures or mechanisms to trap water within you. If you move onto land and are in hot, dry, desert climates water is scarce and you must adapt to survive. This is why desert plants have cutin. I hope that helps! I am a biology major and am currently taking a botany course.
Why is water important to plants animals and people?
Water is essential for plants, animals, and people because it is required for most biological processes to occur. Plants need water for photosynthesis and nutrient uptake, animals need water for digestion and hydration, and people need water to stay hydrated, regulate body temperature, and transport nutrients and oxygen throughout the body.
Which body structure allows mammals to control body fluids and adapt to dry desert conditions?
The kidney is the body structure that allows mammals to control body fluids and adapt to dry desert conditions. The kidney filters waste products from the blood and regulates the balance of water and electrolytes in the body, helping to conserve water and prevent dehydration in desert environments.

Is a desert a landform or body of water?
A desert is neither a landform nor a body of water, it is a biome. There are a variety of landforms in the desert, however.
How can the plants like cactus and acacia live in desert with scarce water?
The plants are designed (or evolved) to store extra water in the plant body or in underground roots when there is rain or water available and the skin of the plants keeps moisture in the plant from evaporating.
How does plants in the dessert survived without water?
In a desert, what little rain there may be is stored in the stems and leaves (succulents), or in the swollen body (cacti). Desert plants may also send down deep roots to seek out any ground water far below.
Where do desert animals gets water?
some animals have designated places in their body to store water, such as the humps of a camel, and some get water from the plants they eat. The plants are able to store their water through guard cells which open and close the stomata, by opening the stomata at night, when its cooler, they are able to keep more water.
A small body of fresh water in the middle of the desert?
A small body if fresh water in the middle of the desert is known as an oasis.
Why dersert plants and animals small?
if your asking "why they are small" its because there isnt much water in the desert so there isnt enough nutrients for the plants to grow big! when it does rain most of the plants store the water inside them, thats why most of the plants like the cactus have spines, to keep others away from their water supply. and the animals are small because of adaption. they had to adapt to the conditions and climate of the desert. smaller the body the less food it needs, and the better it can hide!
What is a narrow body of fresh water in the middle of the desert?
An oasis
What is the name of the body of water south of the Gedrosian Desert?
Arabian Sea
How do desert animals survive without without Water?
desert animals have special things in their body which store water and the body only uses it when it desperartely needs it i also think they dont sweat as much.
How can you survive in the desert with no water?
You can't. The human body needs a constant supply of fresh water, at least at some minimum level. The trick is being able to FIND very small amounts of water in the desert, such as from dew or from plants, or from a solar still. You also need to be ready to capture rainwater (and avoid flash-flooding areas) if it does happen to shower on you.
