Mitochondria is a Greek word. Mitos - thread and chondroitin - granule. (Singular: mitochondrion).
Kolliker first observed mitochondria. Later Altmann named them as Bioplasts. Finally, Benda called them Mitochondria.
Shape:
They are typically sausage-shaped. They can be cylindrical, rod, spherical, granular, filamentous or thread like also.
 
Size:
0.2 micron meters to 2-micron meters.

Location:
They are distributed in cytoplasm bounded by a double membrane envelope. Two membranes are separated by peri-mitochondrial space.

Membrane shape:
1) Outer membrane: smooth
2) Inner membrane: fingers like structure called cristae, which possess a small rounded body called F1 particles or Oxysomes. They help in electron transport.
The interior cavity is filled with a proteinaceous matrix containing lipids, proteins, circular DNA and RNA.

Note:
Mitochondria are absent in bacteria and the red blood cells of mammals. It is the powerhouse of the cell. It stores energy in the form of ATP.
