1. Photosynthesis is the process by which green plants make their own food using sunlight. The food is in the form of glucose, which is stored as starch.

2. To demonstrate that plants need light for photosynthesis, we need to use a de-starched plant. A de-starched plant is one that has been kept in the dark for 24 to 48 hours to use up its stored starch.

3. The reason for using a de-starched plant is to ensure that any starch found in the plant after the experiment is new starch, produced as a result of photosynthesis during the experiment.

4. If we didn't use a de-starched plant, we wouldn't be able to tell whether any starch present was made during the experiment or was already there before the experiment started.

5. After exposing the de-starched plant to light for a certain period, we can test the plant for starch. If the plant has been able to photosynthesize, it will have produced starch and the test will be positive.

6. This shows that light is necessary for photosynthesis. If the plant is kept in the dark, it won't photosynthesize and the starch test will be negative.

7. Therefore, using a de-starched plant is necessary to clearly demonstrate that plants need light to carry out photosynthesis.
