WebStomata are the minute openings, generally found in the epidermis of leaves. They are typically found in the leaves and can also be found in stems and other plant organs. It … Drought inhibits stomatal opening, but moderate drought has not had a significant effect on stomatal closure of soya beans. There are different mechanisms of stomatal closure. Low humidity stresses guard cells causing turgor loss, termed hydropassive closure. Hydroactive closure is contrasted as the whole leaf effected by drought stress, believed to be most likely triggered by abscisic acid.
