How do the trees of the desert adapt themselves to the arid conditions?

उत्तर
They have long tapering roots which go deep to tap water. The trees are stunted as there is not enough rain for tree growth. The thorny branches reduce loss of water by transpiration. The fleshy leaves prevent loss of water by evaporation. The wax on the leaves closes pores.
