An ultrastructural study of the phloem tissues of the stems of bothGnetum gnemon andEphedra campylopoda has shown that they contain only two types of cells—the sieve cells and the phloem-parenchyma cells. The phloem-parenchyma cells belong to the axial parenchyma of the stem. They are nucleate through all their life, contain starch-storing plastids and a normal set of organelles, and are laterally connected to the sieve cells by specialized plasmatic strands. The development of the sieve cell… CONTINUE READING
