What are the adaptations of see weed?

Seaweeds have several adaptations that allow them to thrive in marine environments. They possess a holdfast that anchors them to substrates, preventing them from being swept away by currents. Their flexible structures help them withstand strong waves, while pigments like chlorophyll, carotenoids, and phycobilins enable them to efficiently capture light for photosynthesis at various depths. Additionally, some seaweeds have air bladders that help them float towards sunlight, maximizing their exposure to light for energy production.
