Picture

Method:

1. Place the plan in the dark for two days...

      - This allows all the starch to be used up or move out of the leaves to other parts of the plant.

     - The leaves are said to be de-starched

2. Cover some of the leaves of the plant with aluminium foil

     - This blocks out light and prevents photosynthesis.

    - These leaves will act as a control.

3. Place the plant in a string light for a few hours or overnight if necessary.

    - This allows photosynthesis to take place.

4. Test some of the covered leaves and some of the uncovered leaves for starch, as outlines below.
