The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order. A term for rank-based classification of organisms, in ...
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌændʒiəˈspərmiː /). [5][6] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit.
Plant taxonomy. Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two.
A number of these differences are not unique to the monocots, and, while still useful, no one single feature will infallibly identify a plant as a monocot. [35] For example, trimerous flowers and monosulcate pollen are also found in magnoliids , [ 34 ] and exclusively adventitious roots are found in some of the Piperaceae . [ 34 ]
Orchidaceae is one of the two largest families of flowering plants, along with the Asteraceae. It contains about 28,000 currently accepted species distributed across 763 genera. [3][4] The Orchidaceae family encompasses about 6–11% of all species of seed plants. [5] The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 ...
A cactus (pl.: cacti, cactuses, or less commonly, cactus) [3] is a member of the plant family Cactaceae (/ kækˈteɪsi.iː, - ˌaɪ /), [a] a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. [4] The word cactus derives, through Latin, from the Ancient Greek word κάκτος (káktos), a name ...
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Linnaeus ' Species Plantarum of 1753.
Plants have some of the largest genomes of all organisms. [74] The largest plant genome (in terms of gene number) is that of wheat (Triticum aestivum), predicted to encode ≈94,000 genes [75] and thus almost 5 times as many as the human genome. The first plant genome sequenced was that of Arabidopsis thaliana which encodes about 25,500 genes. [76]
