Injected cumulus cell was enlarged and its mitochondria remained associated closely with the nucleus. The peripheral, or outer, membrane encloses the entire contents of the mitochondrion. There is a slight but statistically insignificant trend for more badly fragmented oocytes to have no detectable mitochondria. Moreover, the mitochondria displayed an altered, rounded morphology and increased electron density. For these cells, the mean distance between mitochondria in processes was 9.35 6 6.50 mm but gaps 10 mm were not uncommon. Typically, these mitochondria are large, swollen and occupy prominent varicosities of the nodal axolemma. The mitochondria were round or oval and contained few cristae. The elongation of the mitochondria may provide the cell with an increased surface area for ion exchange and cellular respiration. Specific examples are, for instance, the fact that the chapter dealing with mitochondria provides illustrations that are far too simplistic. The epidermal matrix 'within' the scale is characterized by the presence of a number of large mitochondria which lie immediately beneath the scale. The mitochondria (m) appear to be swollen and vacuolated and the matrix has totally disappeared. It is considered that the mitochondria are maternally inherited and are, therefore, haploid (clonal). Ultrastructural analyses demonstrated that the blastomere cytoplasm contains a large number of mitochondria and vesicles, several filled with yolk material. These data suggest that mitochondria within the cloud are not only highly localised but also activated. These examples are from corpora and from sources on the web.
