Abstract
The fine structure of plant mitochondria was studied by electron microscopy in the following species: Aloe vera, Elodea canadensis, Glycine max, Yucca glauca, Zingiber officinale, Juniperus communis, Cibotium chamissoi, Psilotum triquetrum, Bryum sp., Funaria hygrometria, Marchantia polymorpha. In all these genera, without exception, the mitochondria were observed to have the same basic structure: a double membrane and a tubular or microvillous structure arising from the folds of the inner membrane. Highly organized lamellated cristae were not present in any of these mitochondria. The diameters of microvilli were measured and ranged from 280Å a to 950Å.
