25. Desert Plant Survival
Adaptations and Survival
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 calledxerophytes. Xerophytes, such as cacti, usually have special means of storing and conserving water. They often have few or no leaves, which reduces transpiration.
Phreatophytesare 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 asperennials, plants that live for several years, andannuals, 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.
26.Differentiate between perinneal plants and yearly plants.
Annual plants are plants with a lifecyclethat lasts only one year. They grow from seed,bloom, produce seeds, and die in one growingseason. They then need to be replanted eachspring.ex.petunias,marigolds, andzinnias.
perennial plants live for more than two years. They return year after year and continue growing until they reachmaturity, which varies by plant but averages three to five years.e:Date trees
