Photosynthesis What do you think of when you hear the word radiation? Light is a form of electromagnetic radiation The difference in types of radiation is that they have different wavelengths Sunlight contains all pigments of visible light In plants, light energy is harvested by pigments that are located in the thylaloid membrane of chloroplasts Electromagnetic Spectrum Photosynthes is occurs in 2 stages 1. Light dependent phase 2. Light independent phase Light Dependent Phase Occurs in the thylakoid Uses water and light Produces ATP, NADPH, and Oxygen http://cnre.vt.edu/dendro/forestbiology/ photosynthesis.swf http://www.stolaf.edu/people/giannini/flas hanimat/metabolism/photosynthesis.swf http://www.compulink.co.uk/~argus/Drea mbio/photosynthesis/photosynthsis%20an imation.htm Light Independent phase Occurs stroma in the Uses ATP, NADPH, and Carbon Dioxide Produces Sugar http://glencoe.mcgrawhill.com/sites/9834092339/student_view 0/chapter39/calvin_cycle.html
