Vedclass · Answer

(A) Anamniotes are vertebrates whose embryos lack an amnion,which is a protective membrane surrounding the embryo. In the classification of vertebrates,fishes (Chondrichthyes and Osteichthyes) and amphibians do not develop an amnion during their embryonic stage. Therefore,they are collectively referred to as Anamniota. In contrast,reptiles,birds (Aves),and mammals develop an amnion and are classified as Amniota.
