Vulva. In mammals, the vulva ( pl.: vulvas or vulvae) consists of the external female genitalia. For humans, it includes the mons pubis, labia majora, labia minora, clitoris, vestibule, urinary meatus, vaginal introitus, hymen, and openings of the vestibular glands. The vulva includes the entrance to the vagina, which leads to the uterus, and ...
Pressed flower decoupage on a miniature chair. Oshibana (押し花) is the art of using pressed flowers and other botanical materials to create an entire picture from these natural elements. [ 1] Such pressed flower art consists of drying flower petals and leaves in a flower press to flatten them, exclude light and press out moisture.
Contents. List of plant genus names with etymologies (A–C) Since the first printing of Carl Linnaeus 's Species Plantarum in 1753, plants have been assigned one epithet or name for their species and one name for their genus, a grouping of related species. [ 1 ] Many of these plants are listed in Stearn's Dictionary of Plant Names for Gardeners.
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /), [5] [6] commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees , shrubs and vines , and most aquatic plants .
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion. The direction of their movement is always opposite to that of the secretion of mucilage. [ 1] It is a polar glycoprotein and an exopolysaccharide.
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
Magnolia is a large genus of about 210 to 340 [a] flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae.The natural range of Magnolia species is disjunct, with a main center in east, south and southeast Asia and a secondary center in eastern North America, Central America, the West Indies, and some species in South America.
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
