Question

Cnidarians exhibit two basic body forms. What are they? How do they differ from each other? Give one example in each.

Answer 1

★Cnidarians possess two morphological phases: Medusa and Polyp

★Both the stages deal with the sexual cycle of cnidarians

★Polyp:

•The primitive stage of the reproductive phase of cnidarians

•They are sessile and can only reproduce asexually

•They produce both polyp and medusa

★Medusa:

•The dominant phase of reproductive cycle of the division Cnidaria.

•They reproduce sexually and are free living

•They only produce medusa

Note:

Only some cnidarians exhibit both the phases
