How do plants survive in hot deserts?
The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
Why do desert plants survive in dry and hot areas?
Here are some of their adaptations: Smaller, fewer, and deeper pores — Many desert plants have smaller, fewer, and deeper pores than other plants. With such pores, hot and dry winds are prevented from blowing directly across the pores and evaporating so much of the plants' water.
How can desert plants survive such dry conditions?
Dealing with the Desert Cactus and other plants that store lots of water to help them through the dry seasons are called succulents. During even light rains, these plants soak up as much water as they can hold, storing the water in large storage areas in roots, leaves, or plant stems.
What are 3 ways plants survive in the desert?
Desert plants have developed three main adaptive strategies: succulence, drought tolerance, and drought avoidance. Each of these is a different but effective suite of adaptations for prospering under conditions that would kill plants from other regions.
How do desert plants adapt themselves to the conditions in the desert Class 6?
These adaptations are: ∙Leaves are modified into spines to minimize the loss of water through transpiration. ∙The stem has a thick cuticle and huge water holding capacity. The thick cuticle helps in reducing transpiration.
How can some plants survive in desert areas Class 4?
Leaves are reduced to spines to reduce water loss through transpiration. Wide and deep roots absorb rainwater on the surface and reach the underground deep water. Sunken stomata to reduce water loss. Fleshy and thick stems to store water and perform photosynthesis, waxy coating on the stem to retain water.
How do plants adapt to dry conditions?
To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns.

There are also a few species of desert plants that have incredibly long root systems that dig up to 80 feet into the ground to search out a water source.
What are some adaptations of desert plants?
A common adaptation among desert plants is a lack of stomata or smaller stomata. Generally, stomata are found in all areas of a plant but on desert plants, they are few and far between. Many succulents use crassulacean acid metabolism which is also known as CAM photosynthesis.
Why are ocotillo plants dormant?
The ocotillo plant is in the perennial category because it sheds its leaves and becomes dormant during the dry months.
Why do cactus die?
The main reason that cacti die is due to overwatering. When in doubt it’s best to limit the amount of watering.
Why are stomata different from other plants?
Stomata pores are different in desert plants because unlike other plants stomata pores are a water loss liability.
What is the name of the plant that holds water underground?
Agave and Yucca are two good examples, but there are a plethora of succulents out there. Water can be held underground in a structure called a tuber . A tuber is an enlarged structure-like-organ that stores extra nutrients, or in this case water.
Why do deciduous plants lose their leaves?
They trap moisture near the plant. Deciduous plants lose their leaves for part of the year, this is convenient for desert plants because that means less water loss. An example is the Ocotillo plant, which sheds its leaves during the dry and hot months and then will regrow them in the cooler months.
How to conserve water?
A creative way to conserve water is a lack of leaves or reduced leaf size. Without the extra extremities, the plant won’t lose as much water to transpiration. Transpiration is the circulation of water throughout the plant which then evaporates into the air. Limiting this step in the survival process means less spent energy and water.
Plants That Are Natural To Desert Lands
Plants like cacti (also known as xerophytes) are native to the desert. Hence, they thrive well and become even more beautiful the longer they are exposed to the sun. They have waxy, thorny leaves, which helps with moisture retention.
How Rain Affects Succulents
We’ve said a lot of times that succulents are drought tolerant plants and they love sunlight exposure. But they also need some rain to regenerate and bloom. So don’t be surprised if your succulents look more brilliant and more dynamic.
Winter Protection For Succulents
Cover your plants with fabrics to increase the temperature. Postpone pruning and don’t remove dried leaves as they can help add more heat whenever snow is forecasted.
An Overview of Desert Plants
There are many deserts across the world. For instance, the Sonoran Desert stretches from Calif to Arizona and Mexico and the Sahara desert in Africa. Deserts experience very high temperatures of up to 40° Celsius, equivalent to 104° Fahrenheit during the day, while the nights are freezing; they can go below the freezing point.
