0 in a cell, a long or round piece found in the cytoplasm (= substance surrounding the nucleus) that produces energy for the cell by breaking down food -- mitochondrium
However, the mechanism underlying the selective destruction of paternally derived mitochondria is unclear.
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.
