CIL:36662, Paramecium multimicronucleatum, cell by organism, eukaryotic cell, Eukaryotic Protist, Ciliated Protist. In Cell Image Library

In a 9-day old culture of stationary phase cells, two or three days post-conjugation, remnants of the previous macronucleus could be found near normal macronuclear bodies. This remnant was identified by its nuclear envelope and a nucleolar body. A sparsely dispersed array of other electron-opaque bodies was present but these were far fewer than in a normal macronucleus. Presumably this body represents a breakdown product of the disintegrating macronucleus that was present before the preceding conjugation that occurred on day 6 or 7. TEM taken on 3/6/80 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 3,500X. Bar = 1µm.
