TLMweb® 10TH CLASS BIOLOGY Hydrilla experiment


10TH CLASS BIOLOGY Hydrilla experiment

10TH CLASS BIOLOGY Hydrilla experiment

Experiment: 

A few twigs of hydrilla are taken and inserted into the funnel. 
The funnel along with the hydrilla twigs is placed in a beaker filled with water. 3. A test tube is filled with water and it is inverted over the funnel. Ensured that the level of water in the beaker is above the level of stem of the inverted funnel. 5. The entire set up is kept in sunlight for nearly 2 3 hours.  The level of water is observed in the test tube. Observation :  After some time small gas bubbles come out of the leaves of hydrilla. 2. We observe that air fills the test tube by lowering the water level. 3. The gas is tested with a glowing splinter. The splinter burns brightly, indicating that the gas accumulated is oxygen. Inference: 
By this experiment, it is proved that hydrilla plant performed photosynthesis and released oxygen.
