A pupil did an experiment to investigate this loss of water by plants.
The apparatus that she used is shown in the diagram.
The rate at which the water level fell (water loss) in the measuring cylinder was measured at regular time intervals, (i) for a plant without the hair dryer, (ii) for a plant with a hair dryer blowing warm air over the leaves, and (iii) for a plant with a hair dryer blowing cool air over the leaves.
The pupil used the data to draw the graph shown.
Match up the three graphs with their corresponding conditions.
1. A = normal, B = cool air, C = warm air
2. A = normal, B = warm air, C = cool air
3. A = cool air, B = warm air, C = normal
4. A = warm air, B = normal, C = cool air

Water vapour evaporates from cells in the leaves of plants and exits the leaves by way of tiny pores in their leaves. What is this process called?
1. Transpiration
2. Respiration
3. Excretion
4. Mutation
Water vapour evaporates from cells in the leaves of plants and exits the leaves by way of tiny pores in their
leaves. This process is called transpiration. This may be investigated by placing a plastic bag over the shoot of a plant as shown. Drops of a liquid appear on the inside of the bag. Which test shows that the drops of liquid are drops of water.

2. Benedict's solution changes the color of the liquid to brick red.
3. The liquid changes the colour of cobalt chloride paper to blue.
4. The liquid changes the colour of litmus paper to red.
