Angiosperm Phylogeny Group - Wikipedia

WebModern angiosperms appear to be a monophyletic group, which means that they originate from a single ancestor. Flowering plants are divided into two major groups, according to the structure of the cotyledons, pollen grains, and other structures. Monocots include grasses and lilies, and eudicots or dicots form a polyphyletic group. WebGeneral characteristics. The angiosperms are a well-characterized, sharply defined group. There is not a single living plant species whose status as an angiosperm or non-angiosperm is in doubt. Even the fossil record provides no forms that connect with any other group, although there are of course some fossils of individual plant parts that ... WebThe order Amborellales is the oldest group of angiosperms, evolutionarily speaking. This group is considered to be the “sister” taxon of all other angiosperms, meaning it diverged before any other angiosperm group did. Because of this, it is an incredibly important group in studying the genomics of flowering plants. firebase auth validation
