Water potential

The main question that came up to my mind is, how does temperature impact water potential? I did some research and found that at high temperature, water potential decreases as evaporation occurs. However at low temperature, water potential becomes negative instead of increasing. As the humidity of the air surrounding the plant rises, it will make the transpiration rate to fall. This means that epidermis that has to do with plants can prevent loss of water and increase the water potential. Stomata can close at high temperature so that the plants can prevent excess water loss or to conserve water. It will open back up to naturally allow some water to evaporate out without losing it all. Plants are very interesting, I actually went to the conservatory for the first time in three years of being here today and I loved everything about it. The scent was aromatic and it was very warm in there probably to keep the plants at the temperature that it needs to be in.
