hii shruti!! here is your answer :-
the physiological process involved here is Transpiration : Loss of water in the form of water vapour from aerial parts of the plant.
(ii) After 2-3 days the level of water falls in test tube A while it remains constant in test tube B.
(iii) The fall in water level in test tube A is due to transpiration by aerial parts which creates a water deficit in the plant. As a result water is absorbed by roots so, water level drops in the test tube A.
(iv) The surface of water is covered with oil to prevent the loss of water by evaporation.
(v) The purpose of setting up test tube B is to show that in the absence of plant there is no change in the level of water.
