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.
The difference in body size between a Cane Corso (Italian mastiff) and a Yorkshire Terrier is over 30-fold; both are members of the same species. Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head and body ...
Contrast gynoecium. Abbreviated A; e.g. A 3+3 indicates six stamens in two whorl s. androgynophore A stalk bearing both the androecium and gynoecium of a flower above the level of insertion of the perianth. androgynous Having male and female flowers in the same inflorescence. androphore The stalk or column supporting the stamen s in certain ...
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]
The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each ...
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.
“There is no perfect size, shape, or color,” Dr. Daneshvar says. The features that do make a difference in the look of one’s vagina are the labia majora and the labia minora, also known as ...
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 ...
