Fill the test tube completely with water. Cover test tube with finger and submerge with open end of test tube in water. Place the beaker in sunlight for at least 20 minutes. Examine the leaf inside the test tube with the hand lens. Notice the bubbles of oxygen on the leaf.
Leaves also take in carbon dioxide from the air.
The water and minerals combine with carbon dioxide, chlorophyll and sunlight to produce sugar and oxygen. Explain the importance of photosynthesis in the life process. In our lesson today, we have learned about the process of photosynthesis. On a sheet of paper write the process of photosynthesis. Carbon dioxide and oxygen.
