Study Notes

Photosynthesis

  • Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of chlorophyll and sunlight
  • The raw materials are carbon dioxide (from the air) and water (from the soil)
  • Sunlight provides the energy for the process
  • Chlorophyll is the pigment in green plants that absorbs sunlight
  • The products of photosynthesis are glucose (food stored in the plant) and oxygen

Absorption of Water and Minerals

  • Water and minerals are absorbed through the plant's roots
