Phycology
Phycology (or
Algology) is the study of
algae. Most algae are
eukaryotic,
photosynthetic organisms that live in a wet environments. They are distinguished from the higher
plants by a lack of true
roots and
leavess. Many species are single-celled and microscopic; many others are
multicellular to one degree or another, some of these growing to large size (for example, seaweeds such as
kelp). Algae are important as
primary producers in aquatic ecosystems.
