Photosynthesis

• Photosynthesis

  When plants make their own food
• Photosynthesis


  Carbon dioxide + water + light energy -> glucose + oxygen
• Photosynthesis is an endothermic reaction
• Stages of photosynthesis


  1. Light energy splits water, releasing oxygen and hydrogen ions

  2. Carbon dioxide gas combines with hydrogen to make glucose
• Photosynthesis


  • Produces glucose
  • Releases oxygen
• Chlorophyll


  Pigment found in the chloroplasts of green plants that absorbs energy from light
• Factors affecting the rate of photosynthesis

  • Oxygen output rate
  • Carbon dioxide uptake rate
  • Carbohydrate production rate
