Recieving light means plants can make more food using photosynthesis, so they will grow larger

Right, the answer is photosynthesis. The plant uses the light and changes it into carbon dioxide CO2. The plant use the CO2 and water H2O to produce sugar and starch which feeds the plant. Check out: http://www.agr.state.nc.us/cyber/kidswrld/plant/nutrient.htm
