Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
Floral sexuality is related to the presence or absence of the reproductive whorls: androecium and gynoecium. Flowers that have both whorls (i.e., will produce both male and female gametes) are said to be perfect, bisexual, monoclinous or, more frequently, hermaphrodites, as is the case with potato flowers (Solanum tuberosum, Solanaceae
The flowers would have tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers grew more advanced, some variations developed parts fused together, with a much more specific number and design, and with either specific ...
Floral formulae are one of the two ways of describing flower structure developed during the 19th century, the other being floral diagrams. [2] The format of floral formulae differs according to the tastes of particular authors and periods, yet they tend to convey the same information.
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.
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.
a sexual system for plants when female, hermaphrodite, and gynomonoecious plants coexist in the same population. [24]: 360 Monoicy: one of the main sexual systems in bryophytes. [17] In monoicy male and female sex organs are present in the same gametophyte. [18] Monoecy: a sexual system in which male and female flowers are present on the same ...
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.
