Multiple Choice

A biologist discovers a new species of plant that grows in wet climates. She hypothesizes that this species would not be able to regulate the size of its stoma (the pores in the leaf of the plant that allows gas exchange) when there are changes in water availability. Which experiment can she perform to best test this hypothesis?

• She waters different plants with different volumes of water and measure the diameter of stoma in each leaf

• She trims a different amount of roots from each plant and measure the amount of glucose produced by each plant

• she grows the plant in greenhouses with various levels of humidity and measures the amount of oxygen produced by each plant

• She places leaves from the plant in solutions containing different amounts of salt and measures the time it takes the leaves to dry out
