(1) The environments of the adaxial and abaxial leaf surface differ in many ways.(2) Juvenile leaves do not have abaxial trichomes whereas adult leaves do.(3) The two adaxial sepals are formed in succession, and the two abaxial petals become visible.(4) An undulating, thick cuticle covers a primary wall of the surface of abaxial epidermal cells.(5) This method resulted in transparent replicas of the adaxial and abaxial leaf surface.(6) A new leaf forms on the adaxial side of a pre-existing leaf and also on the abaxial side of a leaf on flowering shoots.(7) The abaxial surface of the leaf was painted with nail varnish to obtain a transparent surface mould.(8) The locations of each cell type on the abaxial or adaxial leaf epidermis are shown in Fig.1.(9) Major differences in fluorescence responses were detected between adaxial and abaxial tissues of sun leaves.(10) Adaxial and abaxial leaflet surfaces were observed using scanning electron microscopy.
