Plant Parts

This plant, Posidonia oceanica, is a seagrass species that thrives in the Mediterranean Sea, and its structural foundation relies heavily on its underground rhizome. This creeping, horizontal stem acts as the primary anchoring system, extending through the seabed to create vast, stable meadows. Through this rhizome, the plant can spread vegetatively, allowing it to colonize large areas and store essential nutrients required for survival in marine environments.
