Morphology

untreated = treated (transparent) = un + treat + ed

Built by negating the adjective 'treated' (not treated with a reagent/dye), so the meaning is directly derivable.

Etymology

Untreated is made of un- 'not' and treat 'to apply a chemical or dye'. So untreated means 'not given a stain or chemical', which is why an untreated sample often shows no color under a microscope.
