- Label A and B as the following: Egg/ Antheridia/ Archegonia/ ZygoteWhich of these does not pertain to a protostome?a. spiral cleavageb. blastopore is associated with the anusc. coelom, splitting of mesodermd. annelids, arthropods, and molluscse. mouth is associated with first openingAn animal whose development is marked by radial cleavage and enterocoely is. a deuterostome an annelid or mollusk either an acoelomate or eucoelomate none of the above
- Match the description given with either protostome or deuterostome or neither 1)spiral cleavage 2)blastopore becomes the anus 3)schizocoelous coelom formation 4)indeterminate cleavage 5)determinate cleavage 6)blastopore becomes the primitive streak 7)radial cleavage 8)enterocoelous coelom formationDevelopmental patterns between protostomes and deuterostomes Developmental Pattern Protostomes Deuterostomes Cleavage pattern Coelom development Fate of blastoporeGive the order for the life cycle of the hydrozoan, Obelia, starting with the polyp form. Answers Growth into mature polyp Cells grow into Planula. Reproductive polyps form. Medusa buds. Meiosis occurs. Fertilization occurs.
