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.
Dense "beds" of plants and kelp forests provide nurseries for young fish and hiding spots from predators. Aquatic Plants & Algae
Rooted plants hold the sediment together, preventing erosion and keeping the water clear by stopping silt from clouding the column. These are complex, multicellular organisms
Through photosynthesis, they release dissolved oxygen into the water, which is essential for fish and invertebrates. Dense "beds" of plants and kelp forests provide
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
