Raphidocelis Subcapitata
''Raphidocelis subcapitata'', formerly known as ''Selenastrum capricornutum'' and ''Pseudokirchneriella subcapitata'' is a microalga. This microalga presents a curved and twisted appearance like a sickle. The cells are normally presented in a solitary form. It has a length between 8 and 14 μm, and a width between 2 and 3 μm. It is commonly used as a bioindicator species to assess the levels of nutrients or toxic substances in freshwater environments. This species is quite sensitive to the presence of toxic substances including metals and has a ubiquitous distribution, so is broadly used in ecotoxicology. This species has been found to be more competitive than ''Chara vulgaris ''Chara vulgaris'', the common stonewort, is a green alga species in the genus Chara (alga), ''Chara''.

Microalga
Microalgae or microphytes are microscopic scale, microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine life, marine systems, living in both the water column and sediment. They are unicellular organism, unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. Unlike higher plants, microalgae do not have roots, stems, or leaves. They are specially adapted to an environment dominated by viscous forces. Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use the greenhouse gas carbon dioxide to grow photoautotrophically. "Marine photosynthesis is dominated by microalgae, which together with cyanobacteria, are collectively called phytoplankton." Microalgae, together with bacteria, form the base of the food web and provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
