               Notes:


                Desert area is generally very hot and dry with scanty rainfall.


               In cactus, leaves are converted into spines to prevent the loss of water through
               transpiration. Stem does photosynthesis and stores food. It also has well

               developed long root system to draw water from deep under the soil.
