The plasmatocyte has an euchromatic nucleus, a well-developed system of flattened or tubu- lar cisternae of RER, and many free ribosomes (Figs. 2, 6). Mitochondria are approximately three times as frequent as in granulocytes (Table I). Plasmatocytes contain few, if any, large secretory granules. These observations are confirmed by LM serial sections of 12 different plasmatocytes (Fig. 15): two plasmato- cytes contained zero, five contained one, three con- tained two, and two contained three large granules. Plasmatocytes are not affected by endotoxin stimula- Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
