Plural form of carposporangium; structures in red algae that produce and contain carpospores, the microscopic reproductive bodies.
From 'carpospore' + 'angium' (container, from Greek 'angeion'). The plural developed from Latin botanical nomenclature conventions in 19th-century phycology.
These tiny structures in seaweed are like microscopic seed pods—by studying carposporangia, scientists discovered how ocean plants reproduce and spread, fundamentally changing our understanding of aquatic ecosystems.
