Food-Storing Roots
              Plants like carrot, radish, beetroot and turnip

              store food for the plant in their roots. We eat
              these roots as vegetables.


                                                                                    Beetroot             Radish
                                                                                       Food-Storing Roots




               Pull out some grass from the ground. What kind of a root it has? Now, pull out a
               plant of tulsi and observe what kind of a root it has?


              Propagating Roots

              Such  roots  have  buds  close  to  the  surface  of  the  ground.  These  buds  can
              grow into new independent plants, as in the case of cherry and strawberry
              plants.




                During  drought  and  famine,  when  there  is  scarcity  of  food,  people  dig  out  roots
                from the dry soil and eat them.

              Importance of Roots


              g     Roots  absorb  water  and  minerals  from  the  soil  and  send  them  to

                    different parts of the plants.

              g     Heavy rain and a strong wind washes or blows away the topsoil. This is
                    called soil erosion. Roots bind the soil and prevent soil erosion.

              g     Roots play a very important role in the growth of a plant. Roots hold
                    the plant firmly to the soil. Thus, even when a strong wind blows, the

                    plants do not get uprooted.

              Many  human  activities  adversely  affect  the  roots  of  plants.  Activities  like
              construction cause a lot of damage to the roots of the trees planted on the
              roadsides.

              The Shoot System

              The shoot system of a plant is the part of the plant that grows above the

              ground. Stem, leaves and flowers form the shoot system of a plant. All these
              parts carry out different functions and help the plants in different ways.
