Gynoecium (/ ɡ aɪ ˈ n iː s i. ə m, dʒ ɪ ˈ n iː ʃ i. ə m /; from Ancient Greek γυνή (gunḗ) 'woman, female' and οἶκος (oîkos) 'house'; pl.: gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds.
In plants with bisexual flowers, the anthers and carpels may mature at different times, plants being protandrous (with the anthers maturing first) or protogynous (with the carpels mature first). [citation needed] Monoecious species, with unisexual flowers on the same plant, may produce male and female flowers at different times. [citation needed]
A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm.Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do not have a surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones.
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.
Along with modifications involving the above structures two other conditions play a very important role in the sexual reproduction of flowering plants, the first is the timing of flowering and the other is the size or number of flowers produced. Often plant species have a few large, very showy flowers while others produce many small flowers ...
Perennial plants can be propagated either by sexual or vegetative means. Sexual reproduction begins when a male germ cell from one flower fertilises a female germ cell (ovule, incipient seed) of the same species, initiating the development of a fruit containing seeds. Each seed, when germinated, can grow to become a new specimen tree.
In the most common kind of mixed mating system, individual plants produce a single type of flower and fruits may contain self-fertilised, outcrossed or a mixture of progeny types. The transition from cross-fertilisation to self-fertilisation is the most common evolutionary transition in plants, and has occurred repeatedly in many independent ...
Abortion in flowers and developing fruits is a common occurrence in plants. [1] An abortive flower [2] is a flower that has a stamen but an under developed, or no pistil. [3] It falls without producing fruit or seeds, due to its inability to fructify. Flowers require both male and female organs to reproduce, and the pistils and ovary serve as ...
