Mitochondrion

Flat 2D textbook-style cutaway or cross-section of a small oval to bean-shaped mitochondrion with a clear double-membrane structure: a smooth outer membrane, a narrow intermembrane space, and a highly folded inner membrane forming numerous dense cristae as wavy or shelf-like internal ridges projecting inward. The internal matrix is visible as a lighter central region between the darker folded membranes. Typical coloring uses warm tones such as orange, reddish-orange, red, pink, tan, beige, or reddish-brown, sometimes with a pale orange or yellow interior and darker membranes for contrast.
