Cell wall organization of cortical parenchyma of angiosperms observed by the freeze etching technique

  • Takao Itoh


Cell wall organization of the parenchyma in the primary tissue of 3 angiosperms ofPopulus nigra var.italica Koehne,Morus bombycis Koidz. andPhaseolus vulgaris var.humilis Alef. was investigated by the freeze etching technique.

The walls of these parenchyma cells have a crossed polylamellate structure, although a variety of fibrillar angles are found between 2 lamellae adjacent to one another.

On the basis of this evidence, this paper discusses whether the growth of parenchyma cell walls can be interpreted by a simple multinet growth hypothesis.
