Morphology

spore + sac

The meaning 'an organ or structure containing spores' is directly and transparently derived from combining 'spore' (a reproductive cell) with 'sac' (a container-like structure). This noun–noun compounding pattern is straightforward and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the MWE meaning.

Etymology

Spore sac is a small sac or 'bag' in fungi and ferns that holds spores, which are like very small seeds. When the spore sac opens or bursts, it releases the spores, so the name refers to the part that holds and spreads these tiny seed-like cells.
