A. Longitudinal section of dividing cells just after septum formation but before cell wall formation. B. Cross section of septum developing cell. C. Lipid bodies contact to electron-dense bodies enclosed unit membrane. D. A pair of daughter cells during cell wall formation. Note that all lipid bodies in the earlier stage (A) are filled with a similar electron-dense material but in D they became patchy with emergence of electron-dense bodies. ch, chloroplast; G, Golgi body; m-CW, mother cell wall; N, nucleus; n-CW, new cell wall; arrowhead, electron-dense body enclosed by unit membrane; white arrow, septum; * lipid body; arrowhead, electron-dense body enclosed by unit membrane. Scale bars in A,B,D and C: 1 µm and 0.5 µm, respectively.
