The pistils of a flower are considered to be composed of one or more carpels. [ note 1 ] A carpel is the female reproductive part of the flower—usually composed of the style , and stigma (sometimes having its individual ovary , and sometimes connecting to a shared basal ovary) —and usually interpreted as modified leaves that bear structures ...
Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
A bundle or structure of stamens forming one unit in an adelphous flower; for example, the stamen tube around the pistil of Hibiscus. adelphous Having organs, particularly filament s such as stamen s, connected into one or more adelphiae, whether in the form of bunches or tubes, such as is commonly seen in families such as Malvaceae. Usage of ...
Another term, pistil, refers to the ovary as its expanded base, the style, a column arising from the ovary, and an expanded tip, the stigma. [8] Within the stamen, the microsporangium forms grains of pollen, surrounded by a protective microspore, which form the male gametophyte
A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm.Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do not have a surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones.
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
Cross-pollination, also called allogamy, occurs when pollen is delivered from the stamen of one flower to the stigma of a flower on another plant of the same species. [8] Plants adapted for cross-pollination have several mechanisms to prevent self-pollination; the reproductive organs may be arranged in such a way that self-fertilisation is ...
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.
