The microtrabecular lattice and its relationships to other organelles in prokaryotes and eukaryotes--high resolution scanning electron microscopy.

High resolution scanning electron microscopy demonstrated the microtrabecular lattice in bacteria, fungi, plant and animal cells. It is attached to ribosomes and plasma membranes generally, but to other organelles and the nuclear envelope in eukaryotes. The eukaryotic organelle surface substructure is described. Differentiation of real structure from artifacts of fixation, critical point drying and sputter-coating, is discussed.
