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.
In the flowering plants, the gynoecium develops in the central region of the flower as a carpel or in groups of fused carpels. [4] After fertilization, the gynoecium develops into a fruit that provides protection and nutrition for the developing seeds, and often aids in their dispersal. [5] The gynoecium has several specialized tissues. [6]
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals.
A theca is two microspoorangia. The gynoecium (women's house) is the collective term for the female organs (carpels). A carpel is a modified megasporophyll consisting of two or more ovules, which develop conduplicatively (folded along the line). The carpels may be single, or collected together, to form an ovary, and contain the ovules.
A locule (pl.: locules) or loculus (Latin for 'little place'; pl.: loculi) is a small cavity [1] or compartment within an organ or part of an organism (animal, plant, or fungus). In angiosperms (flowering plants), the term locule usually refers to a chamber within an ovary (gynoecium or carpel) of the flower and fruits.
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.
Each carpel has a single placenta corresponding to the weld zone of the carpel leaf. Parietal placentation: occurs in the gynoecium formed by two or more carpels welded by their edges forming a single cavity in the ovary, so that each placenta corresponds to the edges of two contiguous carpel leaves.
In A. thaliana, the C function is derived from one MADS-box type gene called AGAMOUS (AG), which intervenes both in the establishment of stamen and carpel identity as well as in the determination of the floral meristem. [16] Therefore, the AG mutants are devoid of androecium and gynoecium and they have petals and sepals in their place. In ...
