This grayscale electron micrograph showcases the intricate internal structure of a mitochondrion. A roughly oval-shaped mitochondrion dominates the center of the image, surrounded by a double membrane. Invaginations of the inner membrane, known as cristae, are visible, increasing the surface area for ATP production. Darker, granular structures within the mitochondrion likely represent ribosomes. Additional cellular components, possibly other organelles or parts of the cell, are present in the background.
