Is there any kind of acid rain resisting plant?
yes there is some plants have higher tolerance against acid rain, these plants are simply adapted to high acidity with one or more mechanism of the following: thicker cuticle layer >> the acid can cause wax erosion on the plant, the thick cuticle layer can minimize the amount of H2SO4 , HNO3 & HCO3 enter the cell. leaves have no stomata on the upper surface >> stomata are the open gates for H2SO4 & HCO3 to enter the cells, if there’s no stomata on the upper surface, that means little amount of acid can only enter the cell. stomatal closure >> many plants can close their stomata at high concentration of SO2 or CO2 or NO2 in surrounding atmosphere, so they’re closing this “gate” to prevent the enterance of acids. Individual metabolic systems within different species >>> some plants can incorporate sulfur and nitrogen into their S- & N- pools after the enterance of these pollutants the cell which make it less toxic.
