What are the evolutionary changes of angiosperms in comparison with ferns.

Angiosperms evolved from gymnosperms. Those, in turn, descended from ferns, as many scientists believe. The angiosperms have begun to multiply and will spread with the help of seeds. Ferns spread by spores. Also, angiosperms received a fruit during evolution that covered the seeds. This is where the name comes from. A flower is a plant organ that ferns did not have. Also, angiosperms received modified roots and shoots, unlike ferns.
