Marine Plants and Ecosystems

The video discusses marine plants, focusing on seagrasses, salt marsh plants, and mangroves. It explains their adaptations to seawater, ecological roles, and distribution. Seagrasses are mostly found in tropical waters, forming productive meadows. Salt marsh plants, like cordgrass, thrive in estuaries, providing habitats and nutrients. Mangroves, found in tropical regions, have unique root systems and reproductive strategies. The video concludes with a comparison of marine plants and algae, highlighting their ecosystem roles.
