Morphology

Placuna + placenta

This is a Latin binomial (taxonomic) name referring to a species (the windowpane oyster) and the craft material derived from its shell; that specialized referent is not compositionally derivable from the constituent words. Even if a learner knows 'Placuna' (a bivalve genus) and 'placenta' (which is ambiguous or known as an anatomical term), they would need specialist knowledge to infer the meaning 'thin translucent shell/sheets used for decoration', so it is not transparently understandable at B1.

Etymology

Placuna placenta sheets are the thin, see-through plates made from the oyster's shell, and the name may come from old words meaning a 'flat plate' because the shells look like tiny window panes. So these sheets are used for panels, lampshades and other decorative objects that let light through.
