2Chlorophyll & 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.
3Chloroplasts 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.
4High 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.
5PhotosynthesisUses 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
