Fig. 12: mitochondria have tubular cristae (cacodylate buffer)

Mitochondria are organelles enclosed by two membranes in which the inner membrane invaginates to form tubular cristae. The mitochondria shown here are typical of cells in late log phase of growth. This cell was fixed 5 days after transferring the cell to fresh culture. Cacodylate-buffered fixative. EM taken on 5/30/78 by R. Allen with Hitachi HU11A TEM. Neg. 12,250X. Bar = 0.5µm.
