transpiration does not maintain the water potential, as even in very hot weather a lot of water is lost by transpiration and it does not stop to maintain it..... water vapour is lost from stomata and when stomata is kept open carbon dioxide is allowed to enter more efficiently which is an advantage for gas exchangeHello everybody. I have been confused by the following question for a long time...Please help
The answer for this question is D.
But why can't C be right? I thought that stomata are open because of guard cells but not transpiration.
