leaf blade allows for the maximum gathering of the light large surface area for the absorption of carbon dioxide thinness of the blade insures each mesophyll cell gets light Photosynthesis : conversion of light energy to chemical energy First Law of Thermodynamics: Law of the Conservation of Energy energy can neither be created nor destroyed, but it can be converted from one form to another Example: burning paper (paper is made up of cellulose molecules) Cellulose + O2----------------------- carbon + heat energy Potential energy in bonds of cellulose and oxygen molecules = Amount of heat energy released Energy has neither been created nor destroyed;
