Desert Plants Quiz – Masters of Drought

Desert plants survive heat, drying winds and long droughts using clever adaptations. Cacti store water in swollen stems, succulents keep it in fleshy leaves and many plants have waxy coatings to reduce water loss through evaporation.

Spines replace leaves on cacti, shading the plant and deterring thirsty animals. Many desert plants open their pores only at night, when it is cooler, to save water. Roots spread wide to catch rain or reach deep to tap underground water.

Some desert plants are extraordinarily long-lived, such as the welwitschia of the Namib and the creosote bush clones of the Mojave. Others survive as seeds that wait years for rain, then burst into colorful superblooms that transform the desert in weeks.
