The experiment has to be performed in the presence of sunlight. (c) Experiment demonstrating that germinating seeds can respire even in total absence of air. Procedure: 1. 16 Requirements: Fresh Hydrilla plant, beaker,funnel, water, test tube, Sodium bicarbonate, match box etc. The amount of Hydrilla plants taken must be kept constant throughout the experiment.keep a funnel inverted over the plants. Precautions: 1. Experiment 10 : Demonstration of O2 is evolved during photosynthesis in an aquatic plant. In our experiment, we worked with different parameters and it was sought to find out whether they had any bearing on the rate of photosynthesis of an aquatic plant, Hydrilla, using a Wilmott's Bubbler and by counting the number of oxygen bubbles evolved. Theory: Oxygen gas helps in burning. While conducting the experiment ensure that only fresh hydrilla is used.

Keep plants in such a way that all the cut ends of the twigs face upwords. Modest reductions in hydrilla were observed during the experiment (June-August), but quickly increased by 40% one month after operations ceased (September).

Photosynthesis is the process plants (or photoautotrophs) use to convert energy from the sun, carbon dioxide, and water into food (carbohydrates). 16. In addition, the twigs are to be cut in an oblique manner. How to Show Oxygen Is a By Product of Photosynthesis. The Hydrilla sprigs was placed in a large glass funnel such that their freshly cut ends are towards the stem of the funnel. Precautions to Take When Doing Science Experiments They’re the best and most fun part of learning science; they make the subject more interesting and help you understand its principles and theories better; and they bring to life science lessons and eliminate boredom from the classroom. See that the twigs of Hydrilla plant are inside the funnel. Conclusion: From the above experiment, it is clear that oxygen is evolved during photosynthesis. The seeds will float to the … 3. For the experiment … The funnel was inverted into a 500-mL beaker 3/4 filled with water. (1) Take few soaked and peeled off pea seeds and push them into the mouth of a test tube filled with mercury and inverted in a beaker of mercury.
