Algae - 새창
A major group of polyphyletic organisms of extremely varied morphology and physiology, mostly photosynthetic, but distinguished from plants by their complex form of sexual reproduction. They are freshwater and marine, terrestrial and subterranean; some are neustonic (living at the interface of water and the atmosphere). They live in various protozoa and within other plants. They live also in soil and on soil surfaces, on long-persistent snows, and in Antarctic rocks. Thermophilic algae inhabit hot springs. (From Webster, 3d ed; from Bold & Wynne, Introduction to the Algae, 2d ed, pp1-6)
Synonyms : Alga
Algae, Brown - 새창
Predominantly marine algae of the division Phaeophyta, having CHROMATOPHORES containing carotenoid PIGMENTS, BIOLOGICAL. ALGINATES and phlorotannins occur widely in all major orders. They are considered the most highly evolved algae because of their well-developed multicellular organization and structural complexity.
Synonyms : Brown Algae
Algae, Golden-Brown - 새창
Microscopic fresh water algae in the family Chrysophyceae. They share many features with the BROWN ALGAE but are planktonic rather than benthic. Though most are photosynthetic, they are not considered truly autotrophic since they can become facultatively heterotrophic in the absence of adequate light. In this state they can feed on BACTERIA or DIATOMS.
Synonyms : Algae, Golden Brown, Golden-Brown Algae
Algae, Green - 새창
Algae of the division Chlorophyta, in which the green pigment of CHLOROPHYLL is not masked by other pigments. Green algae have over 7000 species and live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater. They are more closely related to the green vascular land PLANTS than any other group of algae.
Synonyms : Green Algae
Algae, Red - 새창
Algae of the division Rhodophyta, in which the red pigment (PHYCOERYTHRIN) predominates. However if this pigment is destroyed, the algae can appear purple, brown, green, or yellow. Two important substances found in the cell walls of red algae are AGAR and CARRAGEENAN. Red algae are thought to be closely related to the prokaryotic CYANOBACTERIA.
