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 ...
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 ]
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 ...
Such male sterility in hermaphrodite populations leads to gynodioecious populations (populations with coexisting fully functioning hermaphrodites and male-sterile hermaphrodites). Cytoplasmic male sterility, as the name indicates, is under extranuclear genetic control (under control of the mitochondrial or plastid genomes).
a sexual system for plants when female, hermaphrodite, and gynomonoecious plants coexist in the same population. [25]: 360 Monoicy: one of the main sexual systems in bryophytes. [18] In monoicy male and female sex organs are present in the same gametophyte. [19] Monoecy: a sexual system in which male and female flowers are present on the same ...
Andromonoecy is a breeding system of plant species in which male and hermaphrodite flowers are on the same plant. [1] It is a monomorphic sexual system comparable with monoecy, gynomonoecy and trimonoecy. [2] Andromonoecy is frequent among genera with zygomorphic flowers, [3] however it is overall rare and occurs in less than 2% of plant ...
This test question appeared on a Luther Burbank High School biology final in June 2024. Student names were obscured by the sources who provided the images to the Sacramento Bee.
Homogamy is used in biology in four separate senses: Inbreeding can be referred to as homogamy. [1] Homogamy refers to the maturation of male and female reproductive organs (of plants) at the same time, which is also known as simultaneous or synchronous hermaphrodism and is the antonym of dichogamy. Many flowers appear to be homogamous but some ...
