Question

difference between metagenesis and metamorphosis

Answer 1

Metagenesis is the phenomenon by which the organism exhibits alternation of generation.For eg :cnidarians especially obelia shows metagenesis where the polyp form (sessile and cylindrical structure) produce medusae (free swimming and umbrella shaped structure) asexually and medusae produce polyp sexually
. 
But in metamorphosis, the organism undergoes several stages which are distinct from that of the adults and these distinct structures undergo abrupt changes in their body structures and internal organs to form the matured adult one. eg: frog,butterfly.

Answer 2

Metagenesis is the alteration of generations between sexual and asexual phases. Metamorphosis produces distinct stages during the life cycle; egg, larva, pupa, and adult. The main difference between metagenesis and metamorphosis is the distinct stages in each type of growth process.
