The receptacle (grey) in relation to the ovary (red) in three types of flowers: hypogynous (I), perigynous (II), and epigynous (III) In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow.
Floral diagramming is a method used to graphically describe a flower. In the context of floral diagramming, the floral axis represents the center point around which the diagram is oriented. [3] The floral axis can also be referred to as the receptacle in floral diagrams or when describing the structure of the flower. [4]
The sterile leaves are modified leaves whose function is to protect the fertile parts or to attract pollinators. [1] The branch of the flower that joins the floral parts to the stem is a shaft called the pedicel, which normally dilates at the top to form the receptacle in which the various floral parts are inserted.
The four main parts of a flower are generally defined by their positions on the receptacle and not by their function. Many flowers lack some parts or parts may be modified into other functions or look like what is typically another part. [ 21 ]
If the hypanthium is absent, the flower is hypogynous, and the stamens, petals, and sepals are all attached to the receptacle below the gynoecium. Hypogynous flowers are often referred to as having a superior ovary. This is the typical arrangement in most flowers. If the hypanthium is present up to the base of the style(s), the flower is ...
Syconium (pl.: syconia) is the type of fruit borne by figs (genus Ficus), formed by an enlarged, fleshy, hollow receptacle with multiple ovaries on the inside surface. [1] [2] In essence, it is really a fleshy stem with a number of flowers, so it is considered both a multiple and accessory fruit.
When it comes to 15-minute weeknight dinners, nothing is better than a simple piece of flaky, tender, savory-sweet brown sugar-glazed salmon. It takes 5 minutes to prep, 10 minutes to cook, and ...
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.
