angiosperms


Angiosperms whose name comes from the Greek and is 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. These types of plants are the largest group of their kind in nature and are made up of trees, shrubs, herbs, wheat, among others. Angiosperms adapt to the environment in which they are found, since 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 they have with the rest of the species. For example, among its distinctive differences are: the decrease in the 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 have been proven thanks to molecular DNA analysis. The way in which they diversified is amazing, given that a series of fossil studies showed that they appeared about 130 million years ago. That was the moment from which large quantities of fossils of various species began to appear, something that until now is very strange, it is as if they had appeared suddenly, something that Darwin called a mystery at the time. Currently about 90% of land plants belong to this group. There are an estimated 257,000 living species.
