- dissection of this region Name the phylum.Salient Features and Classification of Non-chordates Phylum - Coelenterata (Cnidaria), Phylum - Arthropoda The reproductive processes of two organisms were studied. In Animal I, the offspring generated from a detached part of its body, preferably the tail and in Animal Il the offspring was obtained directly from the ovum without fertilization. Thus, on the basis of the information obtained, the animals can be categorized as (a) Hydra and Bee, respectively (b) Planaria and Aphid, respectively (c) Hydra and Aphid, respectively (d) Both (A) and (B)Fertilized egg What structure tells you what stage this is? Blastocoel O Visible nucleus O Archenteron Blastopore O Fertilization envelope
