Final answer:

Desert plants like cacti exhibit adaptations such as thick waxy cuticles and specialized photosynthetic processes to conserve water, enabling them to thrive in arid environments.

Step-by-step explanation:

Plant morphology and behavior are vital for survival in the desert. Xerophytes, such as cacti, have evolved several adaptations to handle the extreme conditions. Their thick waxy cuticle reduces water loss, while specialized photosynthetic processes, such as temporary carbon fixation/storage at night, minimize the need for stomata to open during the hot daytime, conserving precious water.

These adaptations allow the plants to use water more efficiently. Plants also exhibit smaller leaves to reduce evaporation. Such morphological and biochemical strategies enable life in arid environments with limited water access.
