Effect of air pollution on micromorphological structures on leaves of Sida cordifolia L. in the summer (left side: healthy site; right side: polluted site 2) ((a) upper foliar surface showing stomata; (b) lower foliar surface showing stomata with striations at the trichome base; (c) lower foliar surface showing distribution of stomata with developing trichome base; (d) upper foliar surface showing slit-like aperture of stomata; (e) lower foliar surface showing distribution of stomata; (f) lower foliar surface with degenerating trichome).
