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
Rooted plants hold the sediment together, preventing erosion and keeping the water clear by stopping silt from clouding the column. Aquatic Plants & Algae
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. Algae are a diverse group of photosynthetic organisms
Most closely related to land plants, these are common in freshwater. They range from the "pond scum" seen on surfaces to complex branched structures. Classification of Aquatic Plants Rooted plants hold the
These are rooted in the soil underwater, but their upper portions—leaves and flowers—grow above the surface. Common examples include cattails and bulrushes.

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
