Cacti have adapted to hot, dry environments by developing thorns instead of leaves, which reduces water loss by minimizing the surface area exposed to the sun. Additionally, cacti have a waxy coating on their stems to further prevent water evaporation and deep roots that reach underground water sources. This combination of adaptations allows cacti to thrive in arid conditions.
