A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower. These petals attract pollinators, and reproductive organs that produce gametophytes, which in ...
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 for ...
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 ...
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 sporophylls carry ...
Petal. Diagram showing the parts of a mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators.
Stigma (botany) Diagram showing the stigma-style-ovary system of the female reproductive organ of a plant. The stigma is fixed to the apex of the style, a narrow upward extension of the ovary. The stigma (pl.: stigmas or stigmata) [1] is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower.
