Figure 10 Chaetodactylus osmiaemale. TEM. (A) Spermatocyte more advanced than those in Figure 9B, embedded in stroma cell (SC). Note thicker spongy layer (SpL) covering the cell surface, large nucleus (n) and nuage material (asterisks). Peripheral cytoplasm contains many mitochondrial derivatives (md): they are roundish and possess one circular crista. A Golgi body (Gb) is present under the spongy layer neighboring spermatocyte (right bottom). (B) Peripheral parts of two spermatocytes separated by a stroma cell (SC). Compare the thickness
