2 Chlorophyll & Chloroplasts The wavelengths of the visible spectrum are different colors: red, yellow, green, blue, indigo, violet.Photosynthetic organisms capture energy from sunlight with pigmentsChlorophyll reflects green lightIn the fall, as temperatures drop, chlorophyll molecules break down, making the leaves different colors.
3 Chloroplasts contain thylakoids Chloroplasts contain thylakoids. They are arranged in stacks called grana. The liquid part is called stroma.Chlorophyll absorbs visible light very well. A lot of that light energy is transferred to electrons. These electrons make photosynthesis work.
4 High Energy ElectronsElectron carrier-compound that can accept a pair of high-energy electrons & transfer them along with most of their energy to another molecule.1 electron carrier molecule is NADP+. This accepts & holds 2 high-energy electrons & a Hydrogen ion (H+). The NADP+ is converted to NADPH. NADPH carries electrons to other molecules in the body.
5 PhotosynthesisUses the energy of sunlight to convert water & carbon dioxide (reactants) into high-energy sugars & oxygen (products)In symbols: 6CO2 + 6H2O C6H12O6 + 6O2In words: carbon dioxide + water sugars + oxygen
