|---|---|---|
Epithelial cells | a–b | No black pigment, not differential staining |
Air bubble | c | No black pigment Does not absorb the staining well |
Invagination of midgut wall | d–e–f | No black pigment, bubbles inside, asymmetry |
Detached ovary egg | g–h–i | Recognized by the presence of a little knob; pigment covers only one side of the egg; they absorb the staining differentially from the midgut tissue |
