A floral diagram is a schematic cross-section through a young flower. [ 1] It may be also defined as “projection of the flower perpendicular to its axis”. [ 3] It usually shows the number of floral parts, [ Note 2] their sizes, relative positions and fusion. Different organs are represented by distinguishable symbols, which may be uniform ...
A floral formula is a notation for representing the structure of particular types of flowers. Such notations use numbers, letters and various symbols to convey significant information in a compact form. They may represent the floral form of a particular species, or may be generalized to characterize higher taxa, usually giving ranges of numbers ...
Floral axis. The floral axis (sometimes referred to as the receptacle) is the area of the flower upon which the reproductive organs and other ancillary organs are attached. It is also the point at the center of a floral diagram. Many flowers in division Angiosperma appear on floral axes. The floral axis can differ in form depending on the type ...
Floral morphology. Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces. [ note 1] Fertile leaves or ...
This name at once established itself in the language, and America is now called the kwa kee kwoh [花旗國; Fākeìgwok], the "flower flag country"—and an American, kwa kee kwoh yin [花旗國人; Fākeìgwokyàhn]—"flower flag countryman"—a more complimentary designation than that of "red headed barbarian"—the name first bestowed upon ...
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. There are three physiological developments that must occur in order for this to take place: firstly, the ...
Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of symmetry at all, typically because their parts are spirally arranged.
Van de Graaff generator diagram. A simple Van de Graaff generator consists of a belt of rubber (or a similar flexible dielectric material) moving over two rollers of differing material, one of which is surrounded by a hollow metal sphere. A comb-shaped metal electrode with sharp points (2 and 7 in the diagram), is positioned near each roller ...
