- The angiosperms (also called flowering plants) are a major group of land plants, with 250,000 species having been described. Angiosperms comprise one of the two groups in the seed plants, the other group being gymnosperms. The flowering plants cover their seeds by including them in a true fruit.

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 /), 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...
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.
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.
Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crops and ornamental plants are angiosperms. Their success comes from two innovative structures that protect reproduction from variability in the environment: the flower and the fruit.
Structure and function. The wide diversity in the morphological features of the plant body has been discussed above. This section will outline the underlying structural (anatomic) diversity among angiosperms. Vegetative structures. There are three levels of integrated organization in the vegetative plant body: organ, tissue system, and tissue.
