A desert plant (Mexico, S.W. US), it stays inactive
during dry spells and resembles a bunch of dead sticks.
However, when it rains, it quickly grows leaves which
produce food and also flowers in weeks. Shedding its
leaves again after its seeds disperse, it becomes
dormant once more.
Answers
Answer:
To survive, desert plants have adapted to the extremes of heat and aridity by using both physical and behavioral mechanisms, much like desert animals. Plants that have adapted by altering their physical structure are called xerophytes. Xerophytes, such as cacti, usually have special means of storing and conserving water. They often have few or no leaves, which reduces transpiration.
Phreatophytes are plants that have adapted to arid environments by growing extremely long roots, allowing them to acquire moisture at or near the water table.
Other desert plants, using behavioral adaptations, have developed a lifestyle in conformance with the seasons of greatest moisture and/or coolest temperatures. These type of plants are usually (and inaccurately) referred to as perennials, plants that live for several years, and annuals, plants that live for only a season.
Desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available
