Photosynthesis Objective 2:The student will demonstrate an understanding of living systems and theenvironment. (7.8) Science concepts. The student knows that complex interactions occur between matter and energy. The student is expected to: (B) identify that radiant energy from the Sun is transferred into chemical energy through the process of photosynthesis.

Photosynthesis • Photosynthesis changes light energy into food (chemical) energy. http://www.eia.doe.gov/kids/energyfacts/sources/renewable/images/photosynthesis1.gif
Photosynthesis • Begins with (reactants): • Sunlight (radiant energy) • Water (from the ground) • Carbon dioxide (from the air)
Photosynthesis • Ends with (products): • Oxygen • Glucose • Stored chemical energy http://curriculum.calstatela.edu/courses/builders/lessons/less/les4/les4gifs/glucose.gif
Products Reactants CO2 + H2O + light C6H12O6 + O2 From the air Water taken up by roots Energy (sunlight) Glucose Energy Fuel Oxygen
