Assertion.Annelids, mollusks and arthropods are protostomous coelomates. Reason. All these animals have tube-within-tube body plan.

Answer the following: Which phylum onwards all phyla show tube within tube body plan?

In contrast to Annelids, the Platyhelminthes show (a) Radial symmetry (b) Presence of pesudocoel (c) Bilateral symmetry (d) Absence of body cavity

Consider following features: (a) Organ system level of organisation (b) Bilateral symmetry (c) True coelomates with segmentabon of body Select the correct option of animal groups which possess all the above characteristics.
