A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735 This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification.
Plant habit refers to the overall shape of a plant, and it describes a number of components such as stem length and development, branching pattern, and texture. While many plants fit neatly into some main categories, such as grasses, vines, shrubs, or trees, others can be more difficult to categorise.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
In biology, taxonomy (from Ancient Greek τάξις () 'arrangement' and -νομία () 'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics.
Chloranthaceae (/ k l ɔːr æ n ˈ θ eɪ s iː. i / klor-ann-THAY-see-ee) [3] is a family of flowering plants (angiosperms), the only family in the order Chloranthales. [2] It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms.
ABC model of flower development guided by three groups of homeotic genes. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction , a flower.
The Rutherford model is a name for the first model of an atom with a compact nucleus. The concept arose from Ernest Rutherford discovery of the nucleus. Rutherford directed the Geiger–Marsden experiment in 1909, which showed much more alpha particle recoil than J. J. Thomson's plum pudding model of the atom could explain. Thomson's model had ...
