Spermiogenesis and cleistosperm of Carapoia spp. TEM. A C. nairae. Early spermatid, longitudinal section. Note the elongated peN. B C. lutea. Mid- to late spermatid. The heterogenous chromatin condensation as well as the forming CA are visible. C C. nairae. Late spermatid, longitudinal section. The peN is strongly elongated and the posterior centriolar adjunct material begins to develop. D C. nairae. Cross section through the axoneme of a coiled spermatid, showing the organization of the lamellae of the centriolar adjunct material. E C. nairae. Early cleistosperm in the intersection between testes and deferent duct. The secretion sheath is not developed yet
