Gynomonoecy is defined as the presence of both female and hermaphrodite flowers on the same individual of a plant species. [1] It is prevalent in Asteraceae but is poorly understood. [2] It is a monomorphic sexual system comparable with monoecy, andromonoecy and trimonoecy. [3]
Sexual selection is a common concept in animal evolution but, with plants, it is often overlooked because many plants are hermaphrodites. Flowering plants show many characteristics that are often sexually selected for. For example, flower symmetry, nectar production, floral structure, and inflorescences are just a few of the many secondary sex ...
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 ...
Gynodioecy / ˌ dʒ ɪ n oʊ d aɪ ˈ iː s i / is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population. Gynodioecy is the evolutionary intermediate between hermaphroditism (exhibiting both female and male parts) and dioecy (having two distinct morphs: male ...
Hylocereus undatus, a hermaphrodite plant with perfect flowers that have both functional carpels and stamens. The term hermaphrodite is used in botany to describe, for example, a perfect flower that has both staminate (male, pollen-producing) and carpellate (female, ovule-producing) parts. The overwhelming majority of flowering plant species ...
Animals may be dioecious or sequential hermaphrodites. Sex allocation theory also applies to flowering plants, which can be dioecious, simultaneous hermaphrodites, have unisexual plants and hermaphroditic plants in the same population, have unisexual flowers and hermaphroditic flowers on the same plant or to have only hermaphroditic flowers. [3]
Sequential hermaphroditism in plants is the process in which a plant changes its sex during its lifetime. Sequential hermaphroditism in plants is very rare. There are less than 0.1% of recorded cases in which plant species entirely change their sex. [ 65 ]
The sporophyte of a flowering plant is often described using sexual terms (e.g. "female" or "male") based on the sexuality of the gametophyte it gives rise to. For example, a sporophyte that produces spores that give rise only to male gametophytes may be described as "male", even though the sporophyte itself is asexual, producing only spores.
