Phycology (from Ancient Greek φῦκος (phûkos) 'seaweed' and -λογία 'study of') is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms
The list of families in the Fucales, as well as additional taxonomic information on algae, is publicly accessible at Algaebase. [1] The class Phaeophyceae is included within the division Heterokontophyta. [2] This name comes from the Greek word phaios meaning "brown" and phyton meaning plant. [3]
Algae (UK: / ˈ æ l ɡ iː / AL-ghee, US: / ˈ æ l dʒ iː / AL-jee; [3] sg.: alga / ˈ æ l ɡ ə / AL-gə) is an informal term for any organisms of a large and diverse group of photosynthetic eukaryotes, which include species from multiple distinct clades.
Mougeotia is a genus of filamentous charophyte green algae of the order Zygnematales. It is a common component of freshwater aquatic habitats around the world. [ 2 ] Described in 1824 by Carl Adolph Agardh , [ 1 ] its name honors the French botanist Jean-Baptiste Mougeot .
Dinoflagellates are usually positioned as part of the algae group, and form a phylum of unicellular flagellates with about 2,000 marine species. [75] The name comes from the Greek "dinos" meaning whirling and the Latin "flagellum" meaning a whip or lash. This refers to the two whip-like attachments (flagella) used for forward movement.
The parts of a kelp thallus include the holdfast (anchor), stipe (supports the blades) and the blades (for photosynthesis). [2] The thallus of a fungus is usually called a mycelium. The term thallus is also commonly used to refer to the vegetative body of a lichen. In seaweed, thallus is sometimes also called 'frond'.
The term derives from the Greek word δῖνος (dînos), meaning whirling, and Latin flagellum, a diminutive term for a whip or scourge. In the 1830s, the German microscopist Christian Gottfried Ehrenberg examined many water and plankton samples and proposed several dinoflagellate genera that are still used today including Peridinium ...
