The diagram below shows two test tubes A and B. Test-tube A contains a green water plant. Test-tube B contains both a green water plant and a snail. Both test tubes are kept in sunlight. Answer the questions that follow:
(i) Name the physiological process that releases the bubbles of oxygen.
(ii) Explain the physiological process as mentioned above in (i).
(iii) What is the purpose of keeping a snail in test-tube 'B'?
(iv) Why does test-tube 'B' have more bubbles of oxygen?
(v) Give an example of a water plant that can be used in the above experiment.
(vi) Write the overall chemical equation for the above process
The following diagram demonstrates a physiological process taking place in green plants. The whole set up was placed in bright sunlight for several hours. Study the diagram and answer the questions that follow:
(i) What aspect of the physiological process is being examined?
(ii) Explain the physiological process mentioned in (i) above.
(iii) Label the parts numbered 1 and 2 in the diagram.
(iv) Write a well-balanced chemical equation for the physiological process explains in (ii) above.
(v) What would happen to the rate of bubbling of the gas if a pinch of sodium bicarbonate is added to the water in the beaker? Explain your answer.
