  2. 2. Green plants can make food because they have the green pigment called chlorophyll . Chlorophyll helps to trap sunlight for the plant to make food. The process of making food is called photosynthesis . Green plants also need water and carbon dioxide to photosynthesize. Sunlight Carbon dioxide water
  3. 3. The leaves of the green plants are like factories. They make lots of food in the presence of sunlight, water and carbon dioxide. The food that green plants make is called glucose . Glucose is a kind of sugar which is broken down by plants to be used for energy. When too much glucose is made, the excess is stored in plant parts as starch . Glucose  Starch
  4. 4. To test for the presence of starch, the iodine solution test is used. Starch will interact with iodine solution and turn the iodine solution from brown to dark blue . Starch Starch Starch Iodine solution  Iodine solution
