Fig. 3 in Analysis of major sperm proteins in two nematode species from two classes, Enoplus brevis (Enoplea, Enoplida) and Panagrellus redivivus (Chromadorea, Rhabditida), reveals similar localization, but less homology of protein sequences than expected for Nematoda phylum
Fig. 3 Schematic representation of P. redivivus spermatozoa based on transmission electron microscopy. a Morphology of immature and mature spermatozoa. Immature spermatozoon is an unpolarized cell with nucleus devoid of nuclear envelope, mitochondria, and membranous organelles. Mature spermatozoon in female reproductive system is a bipolar cell with anterior pseudopodium and posterior main cell body containing chromatin, mitochondria, and membranous organelles that attached to cell membrane and open to the exterior via pores. Reproduced from Zograf (2014) with the permission from copyright holder (Russian Journal of Nematology). b Chain of conjugated mature spermatozoa in female reproductive system. Abbreviations: N, nucleus; mt, mitochondria; mo, membranous organelles; ch, nuclear chromatin; ps, pseudopodium; mcb, mail cell body
