Investigation Hydroponic Plant Food...

The Results of Our Investigation...

Distilled water is used as a control because we know it does not have any food molecules in it. These are the results with each of the tests for food molecules. Remember Benedict's Solution is used to test for glucose, iodine solution is used to test for starch (complex carbohydrates), Biuret's Solution is used to proteins, and a brown paper bag is used to test for fats.
