Environment drier-stomata

Question

Do plants placed under an environment drier than habitat where they are employed to living have a raise or a lessening in the time throughout which their stomata remain open?

Answer 1

If plants from a moister region were transferred to a drier area probably their stomata would stay closed for a longer time, that is, the time throughout which stomata are open will be reduced to lower the loss of water by the transpiration.
