1 The overall process of photosynthesis produces sugars that store chemical energy. 6CO2 + 6H2O C6H12O6 + 6O2
2 Photosynthetic organisms are producers. Producers make their own source of chemical energy (food).Plants use photosynthesis and are producers.Photosynthesis captures energy from sunlight to make sugars.
3 Chlorophyll is a molecule that absorbs light energy. chloroplastleaf cellleafChlorophyll is a molecule that absorbs light energy.In plants, chlorophyll is found in organelles called chloroplasts.Chlorophyll reflects greenlight!
4 Photosynthesis in plants occurs in chloroplasts. stromagrana (thylakoids)Photosynthesis takes place in two parts of chloroplasts.grana (stack of thylakoids)Stroma (chloroplast fluid)
5 There are 2 stages of photosynthesis Light Dependent Reactions (uses light)(Light Reactions)Light Independent Reactions (doesn’t use light)(Dark Reactions)
6 The light-dependent reactions capture energy from sunlight. take place in thylakoidswater and sunlight are neededchlorophyll absorbs energyenergy is transferred along thylakoid membrane then to light-independent reactions (dark reactions)oxygen is released
7 The light-independent (dark) reactions make sugars. take place in stromaneeds carbon dioxide from atmosphereuse energy from light reactions to build a sugar in a cycle of chemical reactions
