Mitochondria act as microlenses in photoreceptors (VIDEO)

Caption

Mitochondria in cone photoreceptors have a dual purpose: They generate energy for the cell and in a new study they also act as microlenses. This optical role helps concentrate light as it moves from the cell's inner to outer segment. The outer segment is where the light's physical energy is translated into cellular signals.
