The diagram above is an illustration of an experimental setup. Study it and answer the question below;
The setup can measure comparatively the rate of
- evaporation from leaves on a single shoot under different experimental conditions
- salt uptake by shoots from different plants
-
transpiration of a single shoot of a plant under different experimental conditions
- water uptake by roots of different plants
The correct answer is: C
Explanation
The set-up can measure comparatively the rate of transpiration of a single shoot of a plant under different experimental conditions. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, primarily from the leaves. In the illustration, the plant shoot is enclosed in a container, and the amount of water lost from the shoot is measured. By changing the experimental conditions, such as the temperature or humidity, and measuring the transpiration rate under each set of conditions, the set-up can be used to compare the rates of transpiration under different conditions for a single shoot of a plant.
