Their morphological and physiological features consist of fast elongation and extensive root system, high osmotic pressure and endurance of desiccation, the capability to minimize transpiration, and a decrease in the size of the leaf blade. Mammals as a group are not well adapted to desert life due to the fact that they excrete urea, which involves the loss of much water. Succulent plants have thick, fleshy leaves or stems that are capable of retaining water, allowing the plant to survive during dry periods.
