  • Photosynthesis
    • Can only be carried out by green plants and algae.
    • CO2 + HZO > Glucose + Oxygen
    • Chloroplast contain chlorophyll which absorb the sun's light energy which is needed for photosynthesis to occur.
    • 1. Water is taken in  by the leaves and water is taken in by the roots.
      • 2. Chlorophyll traps the light energy needed for photosynthesis.
        • 3. The light energy is used to convert the CO2 and H2O into glucose.
    • Oxygen is released as a by-product of photosynthesis.
    • Glucose can be converted into insoluble starch for storage.
    • By testing leaves with iodine solution we can identify the starch in the leaf to show that photosynthesis has occurred.
