 1. All Plants (Plant Kingdom)  2. Algae (Protist groups: red algae, brown algae, green algae, diatoms, dinoflagellates)  3. Cyanobacteria (Bacteria Kingdom)

 1. water is used up and oxygen is produced  2. Photosystem II captures sunlight and absorbs electrons from water splitting to replace electrons from chlorophyll  3. Photosythem I also captures sunlight and carries electrons from proteins  4. Electron is captured by NADP+ along with H + ions to form higher energy NADPH.

 5. ATP is produced by H+ ions moving through an enzyme called ATP Synthase  6. Light Dependent Reactions occur in green parts of a plant = leaves (and not in the roots underground)  Also: algae and cyanobacteria contain pigments to absorb sunlight and conduct photosynthesis

 1. The 2 high energy molecules produced in Light Dependent Rx are used up: ATP and NADPH  2. CO 2 is used up  3. One organic sugar, glucose, is produced for each 6 CO 2 used.  4. RuBP is regenerated at the end of each cycle and ready for the next CO 2

 1. source of atmospheric oxygen  2. source of all organic molecules, starting with glucose (a carbohydrate)  3. mitigates global warming by absorbing CO 2
