Answer 1

refer the above attachment..

Answer 2

Explanation:

The stomatal pores are largest when water is freely available and the guard cells turgid, and closed when water availability is critically low and the guard cells become flaccid. When the stomata are open, water is lost by evaporation and must be replaced via the transpiration stream, with water taken up by the roots.
