Which department of higher spore plants is characterized by the regressive development of the sporophyte?

The regressive development of the sporophyte is characterized by such a division of higher spore plants as mosses. They represent a dead-end, or blind branch of the location of plants, and also, they are quite similar in appearance and structure to algae.

Mossy are called the only department of the higher flora, which in fact stand apart from other species. All plants are to some extent related to each other by their structure or other characteristics, but not mosses. This is a separate group that has not been subject to any evolutionary development, but on the contrary, the reproduction of these plants and their structure speaks of the most primary forms. The only ones in which sexual forms of development prevail during reproduction.
