To remember photosynthesis makes Glucose
6CO2 + Energy + 6H2O > C6H12O6 + 6O2
Photosynthesis makes glucose and oxygen.
(Energy from light is required.)
After the photographer photos this cow (photosynthesis) she collects the poo to make glue (yes, really). The photographer makes glue (glucose).
In the daytime plant cells receive sunlight into their chloroplasts; water via their roots; and carbon dioxide from the atmosphere in order to produce glucose and oxygen.
CO2 + Energy (light energy) + H20 > Glucose (C6H12O6) + O2
