Anotations

Scope note:

Large and diverse group of simple, typically autotrophic organisms, predominantly aquatic, photosynthetic organisms ranging from unicellular to multicellular forms, such as microscopic single-celled planktonic forms to huge kelps reaching over 100 feet in length; they photosynthesize their own food, though some species also ingest food particles.
