Desert plants: Characteristics
Thriving in environments with minimal rainfall, these plants store water in their tissues, boast unique leaf structures and often germinate rapidly after seasonal rains. Their robust constitution allows them to endure extreme temperatures, making the desert an ideal habitat. A common adaptation involves small leaves, enabling the plant to concentrate water, preventing excessive evaporation. Some plants, like the Barberry, feature leaves transformed into spines, protecting against grazing animals.
Characterised by fewer leaves and branches, these plants boast deep roots that skillfully seek water in the soil. Amidst desertification challenges reducing water availability, these hardy plants ensure their sustenance, with roots delving deep into the ground for efficient water storage.
