(A) $SO_2$ (Sulfur dioxide) is a major air pollutant that enters plants through the stomata. Once inside,it dissolves in the moist cell walls to form sulfite and bisulfite ions. These ions are highly toxic and primarily target the chloroplasts. They cause the degradation of chlorophyll,leading to chlorosis (yellowing of leaves) and a reduction in the rate of photosynthesis.
