Revise: Photosynthesis and respiration
- Revise: Photosynthesis – limiting factors
  Photosynthesis is the process by which green plants use light energy to make their own food. Chlorophyll in the plant cells traps light energy, then carries out a series of reactions.
- Revise: Factors affecting respiration
  Most cell activity requires chemical energy. Respiration is the cellular process of releasing energy from food. Aerobic respiration releases fifteen times more energy than fermentation.
