Abstract: Studying with light microscopy and transmisoion electron microscopy indicated that the stem-tip and leaflet mesophyllous cells and epidermal cells of the G. pentaphyllurn contained the electron density bodies, heterogenous and globoid, 0.2–1.8 μm in diameter, bundled with membrane. Cytochemical dyeing proved that they were protein bodies, distributed mainly in vacuc, le, lined tightly with vacuole membrane, stock together with cytoplasmic masses. This is suggested that they played a role in the cell differentiation and morphogenesis.

Key words: Protein bodies, Electron density bodies, Gynosternrna pentaphyllum
