Take two and mark them (A) and Take about 200 seeds (pea or bean) and soak them in water for more than 24 hours.

Divide the seeds into two equal groups. Kill one group of seeds by boiling them, and then wash them with dilute formalin or carbolic acid to prevent bacterial decay. Put the live germinating seeds in flask (A) and the killed ones in flask (B). Insert a thermometer in each flask and plug their mouths with cotton wool. After a few hours, the thermometer in flask-A will show a higher reading, thus indicating that the germinating (live and respiring) seeds give out heat. The thermometer in flask (B) will not show any rise in temperature. 5. Experiment to demonstrate anaerobic respiration. Take eight to ten soaked and peeled off peas and push them into the mouth of a test-tube filled with mercury and inverted in a beaker of mercury. The seeds will float to the introdu outwarø 1. In (ii)
