Answer:
To prove that oxygen is produced during photosynthesis
Place water plant in a beaker containing pond water.
Cover the plant with short stemmed funnel.
Invert the test tube full of water and cover the stem of the funnel.
While placing the test tube, ensure that the level of the water in beaker is above the level of stem of funnel.
Expose the apparatus to the sunlight.
After few hours, gas bubbles will form and collect in the test tube.
Test the gas in the test tube.
A glowing splinter bursts into the flame shows the presence of oxygen.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants during photosynthesis.
