8-2: PhotosynthesisIn the presence of light, carbon dioxide and water is transformed into carbohydrate and oxygen. CO2 = carbon dioxideH2O = waterC6H12O6 = glucose (carbohydrate)O2 = oxygenReview: Chemical Reactions CO2 + H2O C6H12O6 + O2

What are the products? What are the reactants?

PhotosynthesisCO2 + H2O C6H12O6 + O2

This process occurs in the chloroplast and can occur because of the pigment chlorophyll.A pigment is a protein molecule that can absorb light energy. reactantsproductsThe principal pigment in plants is A. chlorophyll. B. oxygen. C. ADP. D. ATP. E. NADPH. The principal pigment in plants is A. chlorophyll. B. oxygen. C. ADP. D. ATP. E. NADPH. In which organelles would chlorophyll pigments be found?A. vacuoles B. centrioles C. mitochondria D. chloroplasts E.

Fall ColorsIn the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor. http://www.esf.edu/pubprog/brochure/leaves/leaves.htm
