The scope of Mitochondrion is broad, reporting on basic science of mitochondria from all organisms and from basic research to pathology and clinical aspects of mitochondrial diseases.
Mitochondrion is the first journal dedicated solely to research into mitochondria and mitochondrial diseases.
Mitochondrion is a definitive, high profile, peer-reviewed international research journal.

 Encyclopedia article on Mitochondrion [EncycloZine]
"Mitochondrion" literally means 'thread granule', which is what they look like under a light microscope: tiny rod-like structures present in the cytoplasm of most eukaryotic cells.
At one end of the spectrum, the Trypanosome protozoan has one large mitochondrion; by contrast, human liver cells normally have between one thousand and two thousand each.
The number and shape of cristae in mitochondria differ, depending on the tissue and organism in which they are found, and serve to increase the surface area of the membrane.

 Mitochondrial Substructure
The flight muscle of a hummingbird has many cristae in each mitochondrion, because the need is so great.
Thus, each compartment in the mitochondrion is specialized for one phase of these reactions.
This is how oxidation is coupled to phosphorylation:

 [No title]
And so these kind of studies give us some idea of the dynamics and the pathways by which the organelle has evolved.
At the same time, there's been a search for the child that missed out on the playground: the most primitive mitochondrion most like the ancestral symbiotic bacterium.
RB: Now, finally, Michael, you've obviously found something which is rather like the original mitochondrion, but perhaps it's not the granddaddy of them all, perhaps you're going to go back to other protozoons or other organisms, and see if you can find something which is even more primitive.

 NodeWorks - Encyclopedia: Mitochondrion
Finally, mitochondria can fuse with one another, or split in two.
A few cells, such as the trypanosome protozoan, have a single large mitochondrion, but usually a cell has hundreds or thousands of mitochondria.
The membranes of the mitochondrion divide the organelle into two distinct compartments: one within the interior of the mitochondrion, called the matrix, and a second between the inner and outer membranes, called the intermembrane space.

 Mitochondrion - Wikipedia, the free encyclopedia
Thus it appears that there are no primitively amitochondriate eukaryotes, and so the origin of mitochondria may have played a critical part in the development of eukaryotic cells.
A few groups of unicellular eukaryotes lack mitochondria: the symbiotic microsporidians, metamonads, and entamoebids, and the free-living pelobionts.
Mitochondria are sometimes described as "cellular power plants," because their primary function is to convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation.

The work suggests that the Entamoeba mitosome may represent the simplest mitochondrion yet described, and thus it provides a model system for probing which mitochondrial functions are truly essential for eukaryotic cells.
Further experiments performed by the team reveal that the Entamoeba carrier can only transport ADP and ATP, suggesting that it could fuel energy-requiring reactions within the mitosome but might not perform other functions.
As reported by researchers this week, the mitosome can represent a surprisingly pared-down version of the much more sophisticated mitochondrion.

 The Mitochondrion Project
We have begun an effort to identify all components in human heart and human fibroblast mitochondria.

These range from the red crista at upper right which is a single tubule through somewhat more complex cristae with several tubular crista junctions to the inner boundary membrane to the large yellow crista consisting of a large lamellar compartment with many crista junctions.
In this case only four crista are displayed in separate colors to demonstrate the different morphologies observed in this mitochondrion.
