What Adaptations Do Xerophytes Have?

Xerophytes adaptations are based around the need to thrive in dry, arid regions with little rainfall. These adaptations include changes such as a waxy texture to skin, needle-like leaves and roots that spread wide and close to the surface.

The waxy outer layer of these plants keeps water from escaping through the epidermis. The needle leaves have a lower surface area, which conserves more water by preventing its loss through evaporation. Roots that spread wide and close to the surface allow a plant to optimize absorption of limited rainfall. Some xerophytes, however, have very deep roots instead, allowing them to tap into underground water sources. These adaptations allow the xerophytes to survive in places that other plants cannot.
