Plants of the Desert

Drought can occasionally affect plant species in almost every biome, even rain forest, and everywhere plants have made adaptations that minimize water loss. The needlelike leaves of conifers, for example, have evolved to minimize water loss by transpiration (evaporation into the air from exposed plant tissues). Similarly, plants growing in sandy, coastal areas have modified to hold moisture in a salt-ridden environment that tends to draw water from them.
