  • Photosynthesis
    • Plants make their own food by photosynthesis
      • C02+H20 ----> Glucose + O2
      • It is how plants make food which is glucose.
      • Happens in the leaves of green plants
      • Happens inside chloroplasts
        • They contain chlorophyll which absorbs energy in sunlight
    • Leaves are Adapted for Photosynthesis
      • Broad meaning they have a large surface area.
      • They contain lots of chlorophyll in chloroplasts to absorb light.
      • They are full of holes called stomata.
        • Open and close to allow C02 in and 02 out.
        • Also allow water vapor to escape.
    • Limiting factor depends on the conditions
      • The rate is affected by...
        • Light intensity
          • Limiting factor - Stops photosynthesis going any faster.
            • Temperature
        • The concentration of CO2
          • Limiting factor - Stops photosynthesis going any faster.
            • Temperature
      • Which factor is limiting at a particular time changes.
        • At night it is light
        • In winter, it can be temperature
        • C02 is limited if warm and bright.
