Topic: Carpel



  
 Carpel - Wikipedia, the free encyclopedia
The gynoecium, the collective term for all the carpels, is the innermost whorl of the parts of a flower, and in many flowers the other parts (sepals, petals, and stamens) are attached to the receptacle beneath the gynoecium.
A carpel is the female reproductive organ of a flower; the basic unit of the gynoecium.
The carpel of a simple apocarpous gynoecium appears as a folded structure, differentiated into a basal fertile part (ovary) and an upper sterile part (style).

 carpel
Collectively the carpels of a flower are known as the gynoecium.
Each carpel has a stigma which catches the pollen grain.
The anther contains four pollen sacs which burst to release tiny grains of pollen, the male sex cells.

 Fruit Terminology (Part 1)
Carpels are the innermost parts of a complete flower and they are united to form the gynoecium (pistil).
Their carpels do not separate and release the seeds.
It is easy to see that the single carpel of a follicle is a modified, seed-bearing leaf (megasporophyll).

 carpel --  Britannica Concise Encyclopedia - Your gateway to all Britannica has to offer!
Fertilization of an egg within a carpel by a pollen grain from another flower results in seed development within the carpel.
in botany, the surface of the carpel (highly modified leaf) to which the ovules (potential seeds) are attached.
The pistil, centrally located, typically consists of a swollen base, the ovary, which contains the potential seeds, or ovules; a stalk, or style, arising from the ovary; and a pollen-receptive tip, the stigma, variously shaped and often sticky.

Proper development of the carpel margin meristem is thus critical for female reproductive competence and for agricultural productivity in many agricultural varieties.
Reproductive competence of flowering plants requires proper development of the carpel, which is the female reproductive organ of the plant.
The meristematic regions along the margin of the developing carpel generate ovules that will later develop into seeds.

 A New Gnetophyte from the Late Carnian
Probable insect involvement in pollination and the presence of an apical tuft of hair-like appendages on the seed that served in wind dispersal are also consistent with a stem gnetophyte/anthophyte affinity.
In the case of Axelrodia, the transmission tissue (rows of micropapillae aligned with axis of the carpel) developed on the ovary side of paired sterile scales, which became attached to the carpel wall, one on either side of the ventral suture (Cornet, 1989b, Fig.
If the angiosperm carpel and gnetalean macrocupule evolved from a single bract, its larger size and subtending position to one or more ovules helped it to exclude other lower or outside bracts in a phyllotactic spiral or whorl.

 flower - Columbia Encyclopedia® article about flower
Flowers may be staminate (lack carpels), carpellate, or both; staminate and carpellate flowers may appear on the same plant, on separate plants, or in the same inflorescence.
Like twigs, flowers develop from buds, and the basic floral parts (sepal, petal, stamen, and carpel) are in actual fact greatly modified leaves.
A typical flower is a concentric arrangement of these parts attached at their base to the receptacle, the tip of the stem.

The closed carpel is the one major feature that separates the angiosperms from other vascular seed plants.
The closed carpel in a showy flower ensured outcrossing by animal pollinators while increasing pollen exchange with bisexual flowers.
During the evolution of the flower, as the male and female organs of the flower were brought into proximity, the need for protection against self-fertilization was so important that biochemical and mechanical barriers were developed very early in flowering plant ancestors.

 More on Morphology of the Anthophyta
Angiosperms differ from other seed plants in that they enclose their ovules (and seeds) within a carpel.
The carpel is a modified leaf bearing the ovules, but the carpel is folded onto itself, wrapping the ovules inside.
In the center of a typical flower are the carpels, modified leaves which enclose the ovules.

 American Journal of Botany, 15, 4, April, 1928
There are two kinds of carpels in the Cruciferae; a valve, or "sterile" carpel, and a "solid" or "fertile" carpel.
The evidence for this rests upon the course of the bundles in the base of the solid carpel; the solid carpel has evidently contracted, resulting in the disappearance of the loculus.
The inner whorl consists of two solid or closed ovule-bearing carpels, in which the loculus has disappeared by reduction.

Evidence for Sanmiguelia and Archaestrobilus (late Carnian - early Norian) indicates that beetles may have been their primary pollinator (distinctive bite marks, transported anther fragments on carpel, glands or food bodies, etc.).
The reproductive axes of these plants lack petals and sepals, and bear stamens in pairs below conduplicate carpels.
