Detailed explanation-1: -Xerophytes such as cacti are capable of withstanding extended periods of dry conditions as they have deep-spreading roots and capacity to store water. Their waxy, thorny leaves prevent loss of moisture.
Detailed explanation-2: -Moss rose or ‘portulaca’ is a plant that can live for a long time without water. Cactus is also an example of such plants.
Detailed explanation-3: -succulent, any plant with thick fleshy tissues adapted to water storage. Some succulents (e.g., cacti) store water only in the stem and have no leaves or very small leaves, whereas others (e.g., agaves) store water mainly in the leaves.
Detailed explanation-4: -∙Leaves are modified into spines to minimize the loss of water through transpiration. ∙The stem has a thick cuticle and huge water holding capacity. The thick cuticle helps in reducing transpiration. ∙Deep roots help in obtaining water from long distances.
