Plants take up water thorugh the roots, up the stem, and then evaporates through the leaves. This is Transpiration.
Stomata allow the exchange of gas.
The plant will wilt if there is too much water loss, althugh guard cells close hte stomata.
Transpiration takes place more quickly on hot, dry, and windy days, because;
Hot days = more energy causing evaporation
Dry days = the air holds up more water
Windy days = And humidity build up by the plant is blown away.
