HYDRILLA EXPERIMENT
Introduction:The end product of photosynthesis are oxygen(O2),water and starch. So one of the end product is oxygen, which is proved by this experiment.
Aim:To prove oxygen is evolved during Photosynthesis in the presence of sunlight.
Apparatus:Beaker, Water, Test tube ,hydrilla plant twig, Funnel, Sunlight
Procedure :1)place hydrilla plant twig in a Short stemmed funnel and keep in a breaker containing water.
2)Invert a test tube full of water over the stem of the funnel .
3)Place the apparatus in the sun for at least 2-3hours .
4)After some time observe the apparatus .
Observation :1)Gas bubble i. e, oxygen is evolved at the end of the test tube and remove the test tube gently.
2)Test the gas in the test tube by inserting a glowing incense Which would burst into flames.
3)This show the presence of oxygen.
Result :By this experiment we proved that oxygen is produced during photosynthesis in the presence of Sunlight .
