marine algae
Kelp and relatives
Marine algae are photosynthetic organisms that live in saltwater, ranging from microscopic phytoplankton to massive kelp forests.
Unlike land plants, they lack true roots, stems, and leaves, absorbing nutrients directly from seawater.
Seaweed is the common name for larger, visible varieties.
Marine algae produce much of Earth's oxygen and form the base of ocean food chains.
