Flowering plant species with separate, imperfect, male and female flowers on the same individual are called monoecious. Monoecy only occurs in about 7% of flowering plant species. [33] Monoecious plants are often referred to as hermaphroditic because they produce both male and female gametes.
Male and female flowers evolve from hermaphroditic flowers [19] via andromonoecy or gynomonoecy. [20]: 148 In amaranths monoecy may have evolved from hermaphroditism through various processes caused by male sterility genes and female fertility genes. [20]: 150 Monoecy may be an intermediate state between hermaphroditism and dioecy. [21]
Ethylene promotes the production of female flowers. When a plant already has a fruit developing, subsequent female flowers on the plant are less likely to mature, a phenomenon called "first-fruit dominance", [23] and male flowers are more frequent, an effect that appears due to reduced natural ethylene production within the plant stem. [25]
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 ...
The Cucurbitaceae (/ k j uː ˌ k ɜːr b ɪ ˈ t eɪ s iː ˌ iː /), [2] also called cucurbits or the gourd family, are a plant family consisting of about 965 species [3] in 101 genera. [4] Those of most agricultural, commercial or nutritional value to humans include: [citation needed] Cucurbita – squash, pumpkin, zucchini (courgette), some ...
Per Britannica, pumpkin is technically a type of berry called a pepo, which is a fruit that has a hard outer layer and no dividing chambers. (And for the record, squash is also technically a fruit.)
Autoicous – produces male and female sex organs on the same plant but on separate inflorescences. Bract – leaf is present below the flower. Cladautoicous – male and female inflorescences are on separate branches of the same plant. Dioicous – having two forms of gametophyte, one form bearing antheridia and one form bearing archegonia.
