Question

Assertion: Phylum coelentrata exhibit two body form Polyp and Medusa. Reason: Medusa is umbrella shaped and Polyp have sessile form​

Answer 1

Polyp and medusa are the two types of body forms identified in the Cnidarians.

Both sessile and swimming members can be found in Hydrozoa. Sessile structures are called polyps while the swimming forms are called medusa. The key difference between polyp and medusa is that polyp is a fixed, cylindrical structure, representing the asexual stage and medusa is a free swimming, umbrella-like structure, representing the sexual stage.
