The diagram illustrates an experiment used to investigate transpiration. Plant 1 is left uncovered. Plant 2 and its pot are enclosed in a transparent plastic bag. The mass of each plant and its pot is measured. After two hours, the masses are measured once more. What is the result?
- AThe mass of both plants decreases by the same percentage.
- BThe mass of both plants stays the same.
- CThe mass of plant 1 decreases more than the mass of plant 2.
- DThe mass of plant 2 decreases more than the mass of plant 1.
