Fig. 3From: Morphology of the male reproductive system and sperm ultrastructure of the green lacewing, Chrysopa pallens (Rambur, 1838) (Neuroptera: Chrysopidae)Cross-section through early spermatids of C. pallens. A Cross-section through early spermatids. Note two round mitochondrial derivatives (m) and the axoneme consisting of a bundle of microtubule (arrowhead). Arrows indicate plasma membrane. B Cross-section through early spermatids with partially condensed mitochondrial derivatives. Each shows microtubule triplets (arrowhead) and two mitochondrial derivatives (m) with a partial crystallization of the inner material (asterisk). Arrow indicates plasma membraneBack to article page
