In red algae, a specialized structure or cell that produces and contains carpospores, which are asexual reproductive spores derived from the carpogonium.
From Greek 'karpos' (fruit) + 'spore' + 'angium' (container). This technical term developed in 19th-century phycology as scientists studied algal reproduction under microscopes.
A carposporangium is basically a red algae's 'nursery'—it's where thousands of baby spores develop, and understanding these structures was key to unlocking how seaweed populations regenerate and spread across oceans.
