English: Diagram depicting a ray floret structure of family Asteraceae. The ray floret is female with one pistil containing one style, two stigmas, and an ovary with one ovule. Labeled parts are as follows: 1 – corolla (petals) (three petals are joined to form a strap, and in the case of 5 petals, they form a ligule); 2 – style;
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 .
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.
[note 1] A carpel is the female reproductive part of the flower—usually composed of the style, and stigma (sometimes having its individual ovary, and sometimes connecting to a shared basal ovary) —and usually interpreted as modified leaves that bear structures called ovules, inside which egg cells ultimately form. A pistil may consist of ...
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
The ovary is the lower part of the gynoecium that contains the ovules to be fertilized. It is formed by one or more modified leaves called carpels. Inside the ovary there are one or more cavities or locules that contain the eggs waiting to be fertilized. The eggs are inserted into the ovary in an area called the placenta.
The disk floret is bisexual with female parts (one pistil containing one style, two stigmas, and an ovary with one ovule) and male parts (stamen, anthers, and filaments). Labeled parts are as follows: 1 – two stigmas, shown opened (if closed, they would appear as an extension of the style); 2 – style; 3 – five anthers fus...
Stamens may be called the "male" parts of a flower and collectively form the androecium. Finally in the middle there are carpels, which at maturity contain one or more ovules, and within each ovule is a tiny female gametophyte. [3] Carpels may be called the "female" parts of a flower and collectively form the gynoecium.
