(A) The proton transport concept,also known as the active $K^+$ transport theory,was proposed by $Levitt$ in $1974$. This theory explains that the opening of stomata is driven by the active transport of $H^+$ ions out of the guard cells and the simultaneous uptake of $K^+$ ions into them. It successfully integrates the classical $pH$ theory proposed by $Scarth$ with the modern active $K^+$ transport mechanism.
