Algae Division
Algae (sing. alga) are a
large and diverse group of simple, typically
autotrophic
organisms, ranging from
unicellular to
multicellular
forms. The largest and most complex marine forms are called
seaweeds. They
are
photosynthetic,
like plants, and "simple" because they lack the many distinct organs found in
land plants.
