Taxonomy, in a broad sense the science of classification, but more strictly the classification of living and extinct organisms. The internationally accepted taxonomic nomenclature is the Linnaean system created by Swedish naturalist Carolus Linnaeus, who drew up rules for assigning names to plants and animals.

The article draws on internal documents to show that an industry group called the Sugar Research Foundation wanted to "refute" concerns about sugar's possible role in heart disease.

The SRF then sponsored research by Harvard scientists that did just g: Oscillatoriaceae. Taxonomy - Taxonomy - The Linnaean system: Carolus Linnaeus, who is usually regarded as the founder of modern taxonomy and whose books are considered the beginning of modern botanical and zoological nomenclature, drew up rules for assigning names to plants and animals and was the first to use binomial nomenclature consistently ().

Taxonomic studies of Bartramia, Breutelia, Conostomum, and Leiomela (I, III) are included in the project dealing with the bryophyte flora of Western Melanesia (West Irian, Papua New Guinea, Solomon Islands).

Organisms are placed into these categories based on similarities or common characteristics. Some of the characteristics that are used to determine placement are cell type, nutrient acquisition, and reproduction.

The two main cell types are prokaryotic and eukaryotic : Regina Bailey. sing: Oscillatoriaceae.Oscillatoria is a genus of filamentous cyanobacterium which is named after the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source.

At first, because of the limited knowledge of plant structures, artificial classifications, beginning with the most ancient one into herbs, shrubs, and trees, were necessary.
