Photosynthesis (Cambridge (CIE) IGCSE Chemistry)

Photosynthesis

• Photosynthesis is an endothermic reaction

  • Energy is taken in from the environment by chloroplasts / chlorophyll

• The reactants for photosynthesis are carbon dioxide and water

• They are converted into glucose and oxygen 

• Chlorophyll (found in chloroplasts) and energy from light are required for this reaction to occur

• The word equation for photosynthesis is:

Carbon dioxide and water producing glucose and oxygen during photosynthesis
