True or False: For a seed to germinate, it must receive an adequate amount of water.
The saguaro cactus has adapted in numerous ways to protect the water that it collects during rare rainstorms in the desert. It has a vast root system that allows the plant to absorb water near the surface during rainfall. It also has thorns that deter thirsty animals from getting inside the stem of the cactus and drinking its water. The saguaro cactus also has a very thick, barrel-shaped stem used for holding water. Plants that are adapted to these dry places like the saguaro cactus, are called xerophytes. They must collect, store, and conserve large amounts of water to grow and flourish in this harsh environment.
