Chapter 7: photosynthesis Light 1. spectrum, visible light. Violet shorter wavelength has more energy than longer wavelength. 2. More energy= more harm 3. all colors combined= white light II. from light to chemical energy 1. photosynthesis uses light range: 380-750mm 2. tools=pigments (molecules that absorb certain wavelength of light) 3. absorbed vs. reflected light if something reflects wavelength of light you can see that. -color that is reflected is the one that we see the other lights are absorbed. 4. Chlorophyll: most common photosynthetic pigment absorbs violet and red light. -reflects: green light 5. many other photosynthetic pigments: masked by chlorophyll -other (accessory) pigments you can see other pigments before leaves fall off

Unformatted text preview: trees. When colors change they were just being masked. 6. Absorbing light excites electrons in pigments-chloroplasts harnest energy in excited electrons. III. Chlorophyll light absorption-chladophora:-chlorophyll absorbs violet and red end of spectrum IV. chloroplasts 1. organelle for photosynthesis-stroma: fluid inside chloroplasts.-has DNA and ribosomes for chloroplasts-thylakoid membrane: pigment that undergo photosynthesis are here. V. Photosynthesis 1. two reactions 2. Light independent 2. light dependent ATP and NADPH ADP, NADP+ in stroma Thylakoid membrane...
