Question

An apparatus was set up to show that germinating seeds release CO2during respiration.which observation should be made to get the correct results can you give reason for your observations

Answer 1

♠ PROCEDURE :-

An apparatus containing a flask which was made air tight by Cork and KOH was hung in a test tube. A bent tube was joined to a beaker containing water.

♠ OBSERVATION:-

After some hours a steady rise of water level was observed in the tube connected with water beaker.

♠ CONCLUSION:-

This happened because the CO2 which was released by the germinating seeds was absorbed by KOH. This created a vassum in the flask and to fill that empty space water in the beaker started to rise in the tube.

This activity proves the respiration by germinating seeds.
