Plants that live in the marine biome have adapted their physical structure, the way they create food and their reproductive habits. To live in water, plants must be flexible so they can tolerate wave action, and in some cases, float.Continue Reading
Most seaweeds have flexible stems and leaves that move with the current, as well as shallow root structures to hold them in place. Some species have air pockets that help pull the plant toward the surface. An example of the latter is the Bull Whip Kelp, found along the Pacific Northwest Coast. The plants have an air bladder that floats on the surface, pulling the green strands up to the sunlight.
Marine biome plants must have access to sunlight for photosynthesis. Plants take carbon dioxide from the water and convert it to oxygen and sugar. Chlorophyll, the green substance that absorbs sunlight, triggers the process. In marine plants, this substance is usually found in the upper part of the leaves.
Another adaptation of some marine plants is that their seeds can float. On land, seeds are dispersed by birds and other animals. On quiet ponds, flowers like the water lily are pollinated and the seeds dispersed in the normal fashion. In the sea, plant seeds are at the mercy of the waves.Learn more about Botany
