  • Photosynthesis
    • What?
      • Carbon Dioxide + Water -light-> Glucose + Oxygen
        • 6CO2 + 6H2O -light-> C6H12O6 + 6O2
    • Where?
      • The reaction takes place in chloroplasts in palisade cells in leaves in plants.
    • Why?
      • The glucose is used in various ways and mainly respiration.
      • It creates starch. Joined up glucose molecules that are more compact and insoluble. It is a storage form of carbohydrate.
      • It creates lipids which are fats and oils. This is used in seeds.
      • It creates cellulose which is glucose molecules joined together. This is used to build cell walls and it is used to strengthen them.
      • It is used to create amino acids. Glucose combines with nitrate ions which are absorbed from the soil. This can lead onto to protein creation which is many amino acid molecules.
    • Who?
      • Products: glucose and oxygen
      • Reactants: carbon dioxide and water
    • How?
      • The reaction is endothermic which means it uses energy
      • The energy is uses is light energy from sunlight. The light energy is absorbed by chlorophyll.
