A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.
Carbon Dioxide + Water --> Glucose + Oxygen + Energy(ATP) Also photosynthesis only takes place in plant cells due to the fact that they are autotrophs and make their own food.
Reactants: Carbon Dioxide + Water Products: Glucose, Oxygen, and Energy
