Morphology

opercular = operculum (opaque) = operculum + ar

Formed from the noun 'operculum' plus adjective suffix '-ar', but 'operculum' is a rare technical word, so the derivation is not readily guessable to an average B1 learner.

Etymology

Opercular comes from the Latin word operculum meaning 'little lid' and from operire meaning 'to cover'. So the word describes a part that acts like a lid or cover, protecting a soft body or a plant's seeds.
