1. Drought-resistant: Vegetation in deserts typically have adaptations that allow them to survive in arid conditions with limited water availability. This can include deep root systems to access underground water sources, succulent leaves or stems to store water, or reduced leaf surface area to minimize water loss through transpiration.
2. Xerophytic: Desert plants are often xerophytic, meaning they have special adaptations to thrive in dry environments. These adaptations can include thick, waxy cuticles to reduce water loss, small or spiky leaves to minimize surface area exposed to the sun, or the ability to enter dormancy during periods of extreme drought.
3. CAM photosynthesis: Many desert plants utilize a type of photosynthesis called CAM (Crassulacean Acid Metabolism) to conserve water. CAM plants open their stomata at night to take in carbon dioxide and store it as malic acid, which is then converted back into carbon dioxide during the day for photosynthesis. This allows the plant to minimize water loss through transpiration during the hot, dry daytime hours.
4. Sparse and widely spaced: Due to the limited availability of water and nutrients in desert environments, vegetation is often sparse and widely spaced apart. This helps plants avoid competition for resources and allows them to maximize their access to sunlight and water. Desert plants may also have shallow root systems that spread out horizontally to capture as much water as possible from infrequent rainfall events.

1. Succulence: Many plants in desert environments have succulent leaves or stems, allowing them to store water during periods of drought.
2. Drought tolerance: Desert plants have evolved mechanisms to withstand extreme water scarcity, such as thick cuticles, low water loss rates, and the ability to tolerate high salt concentrations.
3. Thorniness: Some desert plants develop thorns to protect themselves from herbivores, as they are often a valuable source of water in arid environments.
4. Deep roots: To access water sources deep underground, many desert plants develop extensive root systems that extend far below the surface.
