Question

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

Answer 1

A : Additional water will be gained and the plant cells will become rigid
B : The stomata will open until too much water is lost
C : Water pressure is going to decease in the guard cells
D : The stomata will close until enough water is lost

The answer D : The stomata will close until enough water is lost

Answer 2

Remember, if CO2 (which is a gas) is needed, then the stomata must open up to let in air. This limits your answers to A and C. If you have plenty of water, how would too much water be lost? I think you can figure out the answer from that.Let me know if this is clear and helps or not.
