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 ...
It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ. [1] The top part of the column is formed by the anther, which is covered by an anther cap . This means that the style and stigma of the pistil, with the filaments and one or more anthers, are all united.
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 .
The gynoecium may present as one or more uni-carpellate pistils or as one multi-carpellate pistil. (The number of carpels is denoted by terms such as tricarpellate (three carpels).) Carpels are thought to be phylogenetically derived from ovule-bearing leaves or leaf homologues ( megasporophylls ), which evolved to form a closed structure ...
Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
The floral axis serves as the attachment point for organs of the flower, such as the reproductive organs (pistil and stamen) and other organs such as the sepals and carpels. [6] The floral axis acts much like a modified stem and births the organs that are attached to it. [ 7 ]

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. Among all living organisms, flowers , which are the reproductive structures of angiosperms , are the most varied physically and show a correspondingly great diversity ...
