Filaments in a high voltage electron micrograph six nanometers or six millionths of a millimeter, thick. Lattice suspends a cell organelle, the lysosome (small dark body at left). The lattice also supports a microruffle: an extension that reaches down like a mitten from the cell surface (top). The small round bodies at a few intersections of the lattice are ribosomes. 100,000 diameters.
