A biologist discovers a new species of plant that grows in very wet climates. She studies the plants stoma, the pores in the lead of a plant that allow for gas exchange, and hypothesizes that this species would not be able to regulate the size of its stoma when there are changes in water availability. Which experiment can she perform to best test this hypothesis? Choose the correct answer. Group of answer choices She trims a different amount of roots from each plant and measures the amount of glucose 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. She waters different plants with different volumes of water and measures the diameter of stoma in each leaf. She grows the plant in greenhouses with various levels of humidity and measures the amount of oxygen produced by each plant.
