ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Seagrasses are flowering plants (angiosperms) that grow in shallow marine environments. They have roots, stems, and leaves and provide critical habitats for marine life like fish, turtles, and seahorses.

Statement 2 is correct: Seagrass meadows are highly efficient carbon sinks, trapping and storing blue carbon (carbon stored in marine and coastal ecosystems), helping to combat climate change.

Statement 3 is not correct: Seagrasses are not related to seaweeds. While seaweeds are macroalgae (non-flowering marine plants without roots, vascular systems, stem), seagrasses are vascular plants with roots and a true vascular system.
