NUTRITION IN PLANTS MAKE THEIR OWN FOOD FROM CARBON DIOXIDE AND WATER BY USING SUNLIGHT IN PRESENCE OF CHLOROPHYLL IS CALLED PHOTOSYNTHESIS. -THE FOOD PREPARED BY LEAVES IS PRESENT IN FORM OF GLUCOSE. THE EXTRA GLUCOSE IS STORED IN FORM OF STARCH. -THE GREEN PLANT CONVERT SOLAR ENERGY INTO CHEMICAL ENERGY.
