AS PLANTS MAKE FOOD IN PRESENCE OF WATER,CO2,LIGHT AS WELL AS CHLOROPHYLL.
C6H12O6+O2=>CO2+H2O (LIGHT AND CHLOROPHYLL)
ALSO THEY HELP IN THEIR SURVIVAL.
Using energy from light, plants chemically combine carbon dioxide and water to create glucose and oxygen. This process is called photosynthesis. Plants also absorb oxygen gas from the air. Like animals, plants needs oxygen to respire
