pigments = chemical that absorbs light 6.1 Photosynthesis pp. 111-113 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?

6.1 Photosynthesis pp. 111-113 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  

CO2 is the main greenhouse gas 6.1 Photosynthesis pp. 111-113 CO2 is the main greenhouse gas Holds in solar radiation Like a greenhouse or car with windows rolled up on a sunny day

Chloroplast = organelle where photosynthesis reacts 6.1 Photosynthesis pp. 111-113 Chloroplast = organelle where photosynthesis reacts * thykaloid = flattened membrane sacs *grana = stack of thykaloids *stroma = liquid solution surrounding grana
