Leaves are important for life to exist on Earth. 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. lay brick patio yourself
