Phycology is the branch of science that deals with the study of algae. It also includes the study of various other prokaryotic organisms like blue-green algae and cyanobacteria. It is also known as algology.
Algae are photosynthetic, eukaryotic organisms that are found in an aquatic environment. They lack true roots, leaves, and stem and do not produce flowers. Phytoplanktons are unicellular while others are multicellular like seaweeds and sargassum.
Important Topics in Phycology
Algae has great ecological importance. Phytoplanktons form a vital part of the food chain. A few algae are commercial sources of iodine, alginic acid, agar, potash, etc. Many large algal species are a food source for many humans. Few species are used in sewage-oxidation ponds. Algal products are also used in insulating materials such as bricks, filters, and scouring powder.
This field became recognized in the 19th and 20th century. Phycologists focus on freshwater or ocean algae. The list of articles mentioned above will help you know more about the branch in detail.
