WebAdd to collection. Background: The relationship between light and plant growth can be demonstrated by exposing leaves to various colors of light. Light supplies the power to carry on photosynthesis, the food-making process in leaves. But the spectrum of light most utilized by a leaf is limited to three distinct colors, red, blue and yellow. http://web01.cabeard.k12.in.us/science/APBiology/bc_campbell_biology_7/medialib/interactivemedia/investigations/LPOS54/LPOS5401/index.html
