- angiosperm, any of about 300,000 species of flowering plants, the largest and most diverse group within the kingdom Plantae. Angiosperms represent approximately 80 percent of all the known green plants now living. The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary.

Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae ( / ˌændʒiəˈspərmiː / ), [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.

Angiosperms have a number of derivedcharacters, which evolved as they split off from the gymnosperms. 1. Flowers Flowers, the reproductive organs of flowering plants, are the most remarkable feature distinguishing them from other seed plants. Flowers, with their colour and their nectar, attract pollinators, which are mostly insects and birds. 95% o...
Molecular evidence indicates that the ancestors of angiosperms diverged from the gymnosperms during the late Devonian, about 365 million years ago. They did not appear in the fossil record until the Mesozoic, almost two hundred million years later. A whole genome duplication (doubling) at 160 million years ago (mya) may have started the ancestral l...

Oct 31, 2023 · Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago. Angiosperms have developed flowers and fruit as ways to attract pollinators and protect their seeds, respectively. Flowers have a wide array of colors, shapes, and smells, all of which are for the purpose of attracting pollinators.
Jun 11, 2018 · The angiosperms, or flowering plants (division Anthophyta or Magnoliophyta), comprise more than 230,000 species and are thus by far the largest division of plants; they represent the dominant group of land plants today. In both vegetative and floral morphology the angiosperms are highly diverse.
The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies.
