Answer:
Animals adapt to their habitat over the course of thousands of years. The same phenomena happens with plants. Plants in arid regions such as the desert must adapt to lack of water. These adaptations are not behavioral like an animal's adaptations, but rather are physical and chemical.
Root Systems
Water and sunlight are essential to a plant's growth, and in the desert, there is plenty of the latter and too little of the former. Plants that depend on a root system to suck water out of the ground must adapt to the barren conditions. Many desert plants have a dual root system. One set of roots acts much as any other plant's root system: It's shallow and searches the immediate surface for any water, as well as keeping the plant grounded. The second set of roots goes deeper, trying to tap into an underground aquifer, which is present in some of the driest desert conditions.
