Context: A flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds., Gentianopsis is a genus of flowering plants in the gentian family known commonly as fringed gentians . These are similar to the gentians of genus Gentiana . Most have flowers which are blue to purple in color . They may be annual or perennial . They are native to Eurasia and temperate North America . Species include : Gentianopsis barbellata - perennial fringed gentian Gentianopsis ciliata - fringe - flowered gentian Gentianopsis crinita - greater fringed gentian Gentianopsis detonsa - windmill fringed gentian Gentianopsis holopetala - Sierra fringed gentian Gentianopsis macounii - Macoun 's fringed gentian Gentianopsis macrantha - grand fringed gentian Gentianopsis simplex - oneflower fringed gentian Gentianopsis thermalis - Rocky Mountain fringed gentian Gentianopsis virgata - lesser fringed gentian Gentianopsis bivigaliaie - Appalachian fringed gentian, Gentianaceae is a family of flowering plants of 87 genera and about 1600 species., Gentiana is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Gentianeae, and the monophyletic subtribe Gentianinae. With about 400 species it is considered a large genus. They are notable for their mostly large, trumpet-shaped flowers, which are often of an intense blue., The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c. 295,383 known species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word ("angeion", "case" or "casing", and "sperma", "seed") meaning "enclosed seeds", after the enclosed condition of the seeds., Subject: gentianopsis, Relation: parent_taxon, Options: (A) angiospermae (B) angiosperms (C) gentiana (D) gentianaceae (E) gentianeae (F) magnoliophyta
