Angiosperms whose name comes from the Greek and scientifically known as Angiospermae, are flowering plants where their seeds have whorls that are a set of three or more leaves that sprout from a stem. This type of plant is the most extensive group of its kind in nature and is made up of trees, shrubs, herbs, wheat, among others. Angiosperms adapt to the environment in which they are found, as they can live in all ecosystems in the world.
These types of plants have a very particular structure, since their flowers and fruits are not the only difference that they have with the rest of the species. For example, among its distinctive differences are: the decrease in gametophyte, which is what determines the life of the plant, as well as a very significant xylem and phloem, more recent than the other tracheophytes, and more efficient in many aspects.
These angiosperms belong to a group of spermatophytes which have very significant morphological characters and which have been proven thanks to molecular DNA analysis. The way in which they diversified is astonishing, given that a series of fossil studies showed that they appeared around 130 million years ago. That was the moment from which large amounts of fossils of various species begin to appear, something that until now is very strange, it is as if they had appeared suddenly, something that Darwin called at the time a mystery. Currently about 90% of land plants belong to this group. They are estimated to be about 257,000 living species.
