& Algae - Aquatic Plants

Through photosynthesis, they release dissolved oxygen into the water, which is essential for fish and invertebrates.

These include the largest seaweeds, such as kelp and sargassum. They are almost exclusively marine and can create massive "underwater forests."

These plants are not attached to the bottom at all. They drift with the current, absorbing nutrients directly through roots hanging in the water. Examples include duckweed and water hyacinth. The World of Algae Aquatic Plants & Algae

These are rooted in the bottom, but their leaves float on the surface. Water lilies are the classic example, utilizing the air-water interface for maximum sunlight.

These live entirely underwater. They often have limp stems because the water provides the necessary buoyancy and support. Pondweeds and coontail are frequently found in this category. They drift with the current, absorbing nutrients directly

These are complex, multicellular organisms. Like land plants, they possess specialized tissues, including roots, stems, and leaves. Most aquatic plants evolved from terrestrial ancestors that returned to the water, retaining vascular systems to transport nutrients.

Primarily marine, these algae contain pigments that allow them to photosynthesize in deeper, dimmer waters where blue light penetrates. Water lilies are the classic example, utilizing the

These organisms act as natural filters, absorbing excess nutrients like nitrogen and phosphorus, which helps prevent toxic water conditions.
