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.
The following adaptations allow plants to survive in the hot desert environment: … The tap roots are much longer and bigger than the plant which is visible at the surface. Spines – some plants have spines instead of leaves, eg cactuses. Spines lose less water than leaves so are very efficient in a hot climate.
Plants adapt to environmental stress by altering their metabolism, flowering, growth, and reproduction; and by migrating toward areas with more favorable climatic conditions. It is difficult to predict the impact of climate change on individual species, which have different capacities to adapt or migrate.
Many have the ability to close leaf pores, called stomata, through which gas and water are exchanged, during drought conditions. Many desert plants, such as the brittlebush, reduce the temperature of their leaves by reflecting sunlight with a thick covering of hairs. Small leaves are another way of reducing water loss.
Answer: The desert plants are called xerophytes while aquatic plants are called hydrophytes. Xerophytes: These plants are adapted for living in extremely dry conditions. They have deep roots, small thin leaves, and waxy thick leathery cuticle to retain moisture.
Stomata are less in number and sunken. Leaves are reduced into spines to prevent loss of water from the surface of leaves. Stomata are less in number and sunken. Both leaves and stems have a thick waxy coating to prevent loss of water in hot weather.
Furthermore, these animals get water as per their requirement from plants and the moisture of meats. Desert plants like cactus are able to store water, thanks to their thick stems. Such plants lack deep roots. Hence, they absorb rainwater because they are close to the surface.
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
Deserts generally have less vegetation. The plants in deserts do not grow very tall and often adapted to store water in their stems, e.g. cactus. They also have reduced leaves to reduce the loss of water through transpiration.

Bluebells are well adapted to life in woodlands. In the spring they flower before the surrounding trees come out in full leaf. This means that they complete their life cycle while light levels are high. Bluebells are able to grow quickly in the spring because they have an energy store in the form of a bulb.
Succulent plants such as cacti, aloes, and agaves, beat the dry heat by storing plenty of water in their roots, stems, or leaves. … For starters, when it does rain, succulents absorb a lot of water quickly. In the desert, water evaporates rapidly, never sinking deep into the soil.
Desert plants tend to look very different from plants native to other regions. They are often swollen, spiny, and have tiny leaves that are rarely bright green. Their strange appearance is a result of their remarkable adaptations to the challenges of the desert climate.
Adaptations. The thick leaves are the main adaptation of the agave. The interior of the leaves holds water to keep the plant alive in the hot desert climates it lives in. The thick coating on the leaves reduces water loss and protects the plant from sunburn in the full desert sun.
Some adaptations in desert plants are:
Nocturnal desert animals keep cool by being active at night, whereas some other desert animals get away from the sun’s heat by digging underground burrows. Other common adaptations seen in desert animals include big ears, light-colored coats, humps to store fat, and adaptations that help conserve water.
Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
Answer: Small leaves will help as they can reduce water loss due to transpiration.
They store water in them. Their roots lie close to the surface of the ground. The roots quickly absorb the moisture from the light rains that occasionally fall. In this way, they fulfill their need for water.
Answer: Soapy was a homeless and jobless man. He needed a place to stay comfortably for three months during the approaching winter. He could get food and shelter at the houses of his known persons but he did not like to answer their odd questions and lose his freedom.
Are the deserts useless ? The deserts are not useless. They are an important part in nature’s great plan.
Adaptations. The lack of rainfall in the desert causes the shrubs to adapt with specialized vegetation to take advantage of every drop of water. … Some shrubs also grow very shallow roots to take advantage of rain, while also relying on a long tap root to reach down to water stored in the ground.
Succulent plants such as cacti, aloes, and agaves, beat the dry heat by storing plenty of water in their roots, stems, or leaves. How? For starters, when it does rain, succulents absorb a lot of water quickly. In the desert, water evaporates rapidly, never sinking deep into the soil.
Examples of Plant Adaptations in Different Environments
Cacti, the fat green body of a cactus is its stem, which is full of water-storing tissue. These adaptations make cacti the most successful plants in a hot, dry climate.
Deserts are similar to tundras cause they both experience extremely high temperatures with little rain. It is also difficult for crops to grow in these areas. Both tundras and deserts get about 10 inches or less of rain per year and lots of bushes as well as trees.
Tundra regions typically get less than 25 centimeters (10 inches) of precipitation annually, which means these areas are also considered deserts. They have long, cold winters with high winds and average temperatures below freezing for six to ten months of the year.
The term biome was born in 1916 in the opening address at the first meeting of the Ecological Society of America, given by Frederick Clements (1916b). In 1917, an abstract of this talk was published in the Journal of Ecology. Here Clements introduced his ‘biome’ as a synonym to ‘biotic community’.Nov 27, 2018
