FIGURE 5.1-5 Transmission electron micrograph of a cross section of a bee ventral ommatidium showing the rhabdom in the proximal part of the dark-adapted ommatidium. Key: ES, extracellular space; PG, pigment granule; PEC, principal endoplasmic cysternae; SLP, secondary pigment cell; M, mitochondria; CB, cytoplasmic bridges. Arrows show the directions of diffusion between SLP and the cytoplasm of the visual cell, and between ES and PEC. (From Gribakin, F.G., in The Compound Eye and Vision in Insects, G.A.
