Ultrastructural analyses demonstrated that the blastomere cytoplasm contains a large number of mitochondria and vesicles, several filled with yolk material.
It is considered that the mitochondria are maternally inherited and are, therefore, haploid (clonal).
The mitochondria (m) appear to be swollen and vacuolated and the matrix has totally disappeared.
The epidermal matrix 'within' the scale is characterized by the presence of a number of large mitochondria which lie immediately beneath the scale.
Note the presence of numerous mitochondria (m) and ribosomes (r) beneath the scale.
Specific examples are, for instance, the fact that the chapter dealing with mitochondria provides illustrations that are far too simplistic.
The elongation of the mitochondria may provide the cell with an increased surface area for ion exchange and cellular respiration.
The mitochondria were round or oval and contained few cristae.
