Although used as a taxonomic category in some pre-Darwinian classifications, e.g., Linnaeus (1753), de Jussieu (1789), Horaninow (1843), Agassiz (1859), Wilson & Cassin (1864), in further classifications, the "algae" are seen as an artificial, polyphyletic group. Physical Boundary. [12], Because of the wide range of types of algae, they have increasing different industrial and traditional applications in human society.

Although cyanobacteria are often referred to as "blue-green algae", most authorities exclude all prokaryotes from the definition of algae. There are few species of Algae that produce toxins and are harmful to fish, finfish, and shellfish, and hence these fishes are harmful if consumed. Agricultural Research Service scientists found that 6090% of nitrogen runoff and 70100% of phosphorus runoff can be captured from manure effluents using a horizontal algae scrubber, also called an algal turf scrubber (ATS). Alginic acid, or alginate, is extracted from brown algae. Varying widely in size, color and form, algae are a diverse group of organisms. In general algae can be referred to as plant-like organisms that are usually photosynthetic and aguatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. The name fucus appears in a number of taxa. Due to this, the species composition of algal populations may shift in the presence of chemical pollutants. Examples: Im going . Inside the cell walls of eukaryotic algae are three main types of organelles: the nucleus, the chloroplasts and the mitochondria. The infoldings, called cristae, have three morphologies: (1) flattened or sheetlike, (2) fingerlike or tubular, and (3) paddlelike.

More modern algaculture applications extend the food traditions for other applications include cattle feed, using algae for bioremediation or pollution control, transforming sunlight into algae fuels or other chemicals used in industrial processes, and in medical and scientific applications. HM Land Registry plans: boundaries (practice guide 40, supplement 3) Phylogeny based on plastid[19] not nucleocytoplasmic genealogy: These groups have green chloroplasts containing chlorophylls a and b. [72] To detect these changes, algae can be sampled from the environment and maintained in laboratories with relative ease.
