Photosynthesis

  • Green plants make food by photosynthesis.
  • Photosynthesis occurs in the leaves of a plant.
  • The green chemical chlorophyll is needed for photosynthesis.
  • Chlorophyll traps light energy and uses it to combine carbon dioxide and water. This forms glucose and oxygen.
  • Leaves have air spaces between their leaves called stomata.
  • The three things needed for photosynthesis to occur are light, water and carbon dioxide.
  • Carbon dioxide enters the leaf from the air.
  • Water is absorbed through the roots from soil.
  • The word equation for photosynthesis is :
