In angiosperms (flowering plants), the term locule usually refers to a chamber within an ovary (gynoecium or carpel) of the flower and fruits. Depending on the number of locules in the ovary, fruits can be classified as unilocular (uni-locular), bilocular, trilocular, or multilocular. The number of locules present in a gynoecium may be equal to ...
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 ...
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 seam or face at which two carpel s adhere. See also fissure and suture. community An ecological assemblage of plants that characteristically occur together. compound Composed of several parts, e.g. a leaf composed of multiple leaflet s, a gynoecium composed of multiple carpel s, or an inflorescence made up of multiple smaller inflorescences.
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]
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 ...
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 ...
