[8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
The androecium is one of the fertile cycles of flowers. The parts that make up the androecium are called stamens whose function is the generation of male gametophytes or pollen grains. The stamens are highly modified leaves formed by a foot that is inserted into the receptacle of the flower, called filament, and a distal portion called anther ...
Stems have several main functions: [3] Support for and the elevation of leaves, flowers, and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits. Transport of fluids between the roots and the shoots in the xylem and phloem. Storage of nutrients. Production of new living tissue.
Bract – the leaf- or scale-like appendages that are located just below a flower, a flower stalk, or an inflorescence; they usually are reduced in size and sometimes showily or brightly colored. Calyx – the whorl of sepals at the base of a flower, the outer whorl of the perianth.
Having flowers or fruits growing directly from a tree's trunk. [27] cauline Borne on an aerial stem or caulis, as with leaves, flowers, or fruits (when applied to the latter two organs, usually referring to older stems. caulirosulate Borne at the end of the stem or caulis, as with leaves or bracts. cell 1.
The shoot apical meristem is the site of most of the embryogenesis in flowering plants. [citation needed] Primordia of leaves, sepals, petals, stamens, and ovaries are initiated here at the rate of one every time interval, called a plastochron. It is where the first indications that flower development has been evoked are manifested.
The stamens arise between the petals and the disk. Hypanthium in Rosa Narcissus pseudonarcissus, showing from the upper bend to the tip of the flower: spathe, ovary, hypanthium, tepals, corona. In myrtles, the hypanthium can either surround the ovary loosely or tightly; in some cases, it can be fused to the walls of the ovary. It can vary in ...
The flower of flowering plants is sometimes referred to as a bisexual strobilus. Stamens include microsporangia within the anther , and ovules (contained in carpels ) contain megasporangia . Magnolia has a particularly strobiloid flower with all parts arranged in a spiral, rather than as clear whorls.
