F, fissures; Ml, middle lamella; OB, oil body; Cl, coalesced lipid; Fl, free lipid. Arrows point to intact cells underneath the fractured layer of parenchyma tissue; note coalesced lipid (OB) from fractured cells and free lipid on the peripheral edge of the tissue. Scale bar A1–C2 = 20 µm; A2–C2 = 50 µm.
