CO₂ Release in Germinating Seeds Respiration

To prove that carbon dioxide (CO₂) is released during respiration by germinating seeds.

Materials Required • Germinating seeds (pea/gram) • Conical flask • Cork

• Delivery tube • Test tube with lime water Procedure (Simple Steps)

1. Take a conical flask and put germinating seeds into it. 2.

Close the flask tightly using a cork. 3. Fix a delivery tube

to the cork. 4. Dip the free end of the tube into a test tube containing

lime water. 5. Keep the setup undisturbed for some time. Observation

• The lime water turns milky. Conclusion • Lime water turns milky due to carbon
