Figure 7: Semithin section of ovotestis of older Macrochlamys indica. (A) Large oocyte is surrounded by a thin follicular cell layer (black arrow) with nucleus and nucleolus. White arrow indicates spermatids. (B) An acinus showing one large oocyte (black arrow). White arrow indicates a bunch of sperm. A magnified view of interacinar space with many interstitial cells (white arrow head) is shown in box. (C) An acinar part showing spermatocytes, spermatids (arrow) and there is no Sertoli cell pocket formation between these cells. (D) Transmission electron microscopy of the ovotestis of older snails, showing the associations of spermatocytes with adjacent Sertoli cell. Sertoli cell has no membranous digitations around the cell membrane. (E) Developed spermatids of older snails. n = nucleus; ot = oocyte; S = Sertoli cell; sc = spermatocyte.
