Answer 2

HYDROZOA is the class of Coelenterate which exhibits Metagenesis

Explanation:

• METAGENESIS- It refers to Alternation of generation between sexual and asexual reproduction. It is the phenomenon in which organism reproduce asexually, followed by sexual mode of reproduction. Both the forms are diploid in metagenesis there this is also called False Alternation of Generation.

In COELENTERATES or CNIDARIANS, they show metagenesis. They reproduce by two forms- POLYPS and MEDUSAE.

POLYPS-

• It reproduces ASEXUALLY.              
• It is SESSILE and is attached to the substratum              

• It reproduces ASEXUALLY by budding to produce MEDUSAE

MEDUSAE-

• It reproduces SEXUALLY.
