Answer:
Cactus reserve rainwater in the essence of both stems and roots.
Explanation:
That plant depends on chlorophyll in the external tissue of their surface and stems to manage photosynthesis for the forming of food. Spikes defend the plant from beings, shelter it from the day-star and also obtain precipitation. Extensive shallow root operations are normally spreading, acknowledging the fast recovery of large volumes of rainwater when it showers. Because they save water in the center of both stems and roots, cactus is well-suited to dry weathers and can last years of dryness on the rainwater gathered from an only rainfall.
