Photosynthesis

• Photosynthesis happens in the chloroplasts of plants
• Carbon dioxide + water -> glucose + oxygen
• Photosynthesis is an endothermic reaction
• Factors affecting photosynthesi:

  • Temperature - optimum temperature needed for enzymes to work
  • Light intensity - light transfers the energy needed for photosynthesis
  • Carbon dioxide - one of the reactants needed
• Investigating photosynthesis:

  • The closer the pondweed is to the light, the more photosynthesis occurs and therefore more oxygen is produced
