A cyclic flower is a flower type formed out of a series of whorls; [1] sets of identical organs attached around the axis at the same point. Most flowers consist of a single whorl of sepals termed a calyx; a single whorl of petals termed a corolla; one or more whorls of stamens (together termed the androecium); and a single whorl of carpels termed the gynoecium.
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.
The morphology of most flowers (called cyclic flowers) is based on four types of whorls: The calyx: zero or more whorls of sepals at the base; The corolla: zero or more whorls of petals above the calyx; The androecium: zero or more whorls of stamens, each comprising a filament and an anther
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 of plant.
In dicot root, the vascular cambium is completely secondary in origin, and it originates from a portion of pericycle tissue. [citation needed] The pericycle regulates the formation of lateral roots by rapidly dividing near the xylem elements of the root. [2] It has been known to often be confused with other parts of the plant.
Disk – an enlargement or outgrowth from the receptacle of the flower, located at the center of the flowers of various plants. The term is also used for the central area of the head in composites where tubular flowers are attached. Epicalyx – a series of bracts below the calyx. Floral axis – Floral envelope – the perianth [16] Flower –
It can be useful for flower identification or comparison between angiosperm taxa. Paleontologists can take advantage of diagrams for reconstruction of fossil flowers. Floral diagrams are also of didactic value. [1]: xiii Relation of a plant material (Campanula medium) to the floral diagram. Black dashed line shows the cross-section. 1 ...
Plant structures, including, roots, buds, and shoots, that develop in unusual locations are called adventitious. Such structures are common in vascular plants. [citation needed] Adventitious roots and buds usually develop near the existing vascular tissues so that they can connect to the xylem and phloem. However, the exact location varies greatly.
