Question

a) What does the activity in the above fig tell about? b) In which direction does the test tube move? ​

Answer 1

Answer:

(i) In the given experiment, bubbles of oxygen are released due to the process of light reaction of photosynthesis. 

(ii) Photosynthesis is a process in which green plants (plant cells having chlorophyll) take in carbon-dioxide and water in presence of sunlight to produce glucose. It releases oxygen gas during the photolysis of water which is a part of the light reaction.

(iii) The purpose of keeping the snail in the test tube B is the production of carbon dioxide which is used by the plant.

(iv) Test tube B have more bubbles of oxygen because the rate of photosynthesis is more in test tube B as it gets more CO2 from the snail.

(v) Hydrilla is a water plant which is used for such experiments.
