What characteristics would plants in a dessert have?

Answer 1

Some plants have long roots to get water deep in the soil, or branched roots to get water over a wide area. With thick waxy layer on the stems and leaves, water can be retained and the tissues are protected from strong sunshine. Some plants have pin-like leaves to reduce water loss. Many desert plants are succulents and they store water in their swollen stems or leaves.

Some desert plants are the " drought evaders" . They exist as seeds before the rain comes, and grow when it rains. They flower quickly to produce seeds and then die. There are " drought resisters" --- perennial plants that possess the abilities of storing water, locating underground water or minimizing the use of water by various measures.
