Presentation on theme: "pigments = chemical that absorbs light"— Presentation transcript:

1 pigments = chemical that absorbs light
6.1 Photosynthesis pp pigments = chemical that absorbs light Light is combination of visible colors (ROY G BIV) If pigment absorbs a color, you don’t see it You see colors it reflects (p.113) Who is Roy G Biv?

3 6.1 Photosynthesis pp. 111-113 PIGMENT COLORS ABSORBED REFLECTED
YOU SEE Chlorophyll a Purple, orange, red Green, blue, yellow Chlorophyll b Carotenoids anthocyanins

7 6.1 Photosynthesis pp Carbon fixation = carbon from the atmosphere (CO2) is held by living things “fixed” into the body Living things change CO2 into organic carbon (sugars, starches, & oils) CO2 is released back into atmosphere when dead things rot or are burned Burning fuels Decaying plants Flatulence/burping

8 CO2 is the main greenhouse gas
6.1 Photosynthesis pp CO2 is the main greenhouse gas Holds in solar radiation Like a greenhouse or car with windows rolled up on a sunny day

9 Chloroplast = organelle where photosynthesis reacts
6.1 Photosynthesis pp Chloroplast = organelle where photosynthesis reacts * thykaloid = flattened membrane sacs *grana = stack of thykaloids *stroma = liquid solution surrounding grana
