Aquatic Plants & Algae -

Primarily marine, these algae contain pigments that allow them to photosynthesize in deeper, dimmer waters where blue light penetrates.

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 Primarily marine, these algae contain pigments that allow

These include the largest seaweeds, such as kelp and sargassum. They are almost exclusively marine and can create massive "underwater forests." They drift with the current, absorbing nutrients directly

Rooted plants hold the sediment together, preventing erosion and keeping the water clear by stopping silt from clouding the column.

Aquatic plants and algae are the silent architects of underwater worlds. While they share the same watery habitats and both perform photosynthesis, they belong to entirely different biological lineages. Together, they form the foundation of aquatic food webs, oxygenate the water, and provide critical structure for diverse marine and freshwater life. The Biological Divide

Algae are a diverse group of photosynthetic organisms that lack true roots, stems, or leaves. They range from microscopic single-celled organisms (phytoplankton) to massive, multicellular structures like giant kelp. Unlike plants, algae absorb nutrients directly from the water through all parts of their body. Classification of Aquatic Plants
