Fig. 7

Transmission electron micrographs illustrate the ultrastructure construction of G. mellonella larvae midgut from the control (A–C) and CdO NP-treated group (A`- C`). (A and B) showing typical digestive cells with large nuclei and apical cytoplasm with numerous organelles. (C) presenting the basal cytoplasm of the midgut digestive cells with normal basal lamina. (A`) illustrating degenerating digestive cells lacking the characteristic organelles of the apical cytoplasm with obvious vacuolation, and distorted microvilli (purple braces). (B`- C`) demonstrating the necrotic damage of midgut cells (asterisk *), rupture of cell membranes, and cytoplasmic lysis. Lumen (L), digestive cell (DC), microvilli (Mv), nucleus (N), autophagic structure (au), basal lamina (Bl), vacuole (V). In all photos, the scale bar = 2.0 µm and magnification X 2000.
