2 Iаn wаnted tо investigаte hоw gas exchange in a flоwering plant changed with light intensity. He set up an experiment using four tubes. Each of the tubes contained orange hydrogen-carbonate indicator solution and was sealed with a cork. Ian added a fresh leaf to tubes A, B and C. Tube D had no leaf. The tubes were then left in the following conditions: Tube A was placed in direct sunlight. Tube B was covered with aluminium foil to prevent any light entering the tube. Tube C was covered with thin cloth which allowed some light to enter the tube. Tube D was also placed in direct sunlight. He left the tubes in the laboratory for one hour and then returned to look at the colour of the indicator solution in the tubes. 2.1 Suggest why tube D did not have a leaf. (2) 2.2 Give two variables that Ian should keep constant in his investigation. (2) 2.3 State the purpose of Tube D in the investigation. (1) 2.4 Ian recorded his results in a table.
