Question

If carbon dioxide is needed for photosynthesis and water is plentiful, which of the following is likely to occur? A. The stomata will close until enough water is lost. B. Water pressure is going to decrease in the guard cells. C. Additional water will be gained and the plant cells will become rigid. D. The stomata will open until too much water is lost

Answer 1

It's B. Water pressure is going to decrease in the guard cells.

Answer 2

The correct answer should be D. The stomata will open until too much water is lost. What happens is that the gas can diffuse and that the excess water can leave, meaning in laymen terms that the water exits so there's more room for carbon dioxide. When the process is done the stomata closes back up and things go back to normal.
