The diagram represents a certain physiological process in plants.
Name the process.
Three plants A, B and C are placed in a beaker containing coloured water. The water in each beaker is covered with a layer of oil. The leaves were removed from plant B while plant C was exposed to strong light.
(a) In which plant, A. B or C, would the water move up fastest?
(b) In which plant would water move slowly?
(c) Why is the water covered with oil?
(d) What is being investigated by this experiment?
State the use of capillary tube in the given apparatus.
