Photosynthesis Reactants (what’s needed) *Water *Carbon dioxide (CO²) *Sunlight energy

Where does photosynthesis take place? *In the Chloroplast (Chlorophyll – captures the sun’s energy here)

Photosynthesis – What does it produce? oxygen sunlight *Products water Food *glucose *sugar *carbohydrates Carbon dioxide
