Reproduction, Development and Metagenesis in Cnidaria -

  • The reproduction occurs through both asexual and sexual means. 
  • Budding is the common method of asexual reproduction. 
  • Sexual reproduction occurs through the formation of gametes. 
  • Cnidarians exhibit metagenesis, i.e., alternation of generation. There are two body forms:
  • Polyp: It is fixed and sessile form with mouth and tentacles facing upwards. It reproduces asexually by budding to form the second body form.
  • Medusa: It is free-floating form with mouth and tentacles facing downwards. It reproduces sexually to form polyps. 


 

Polyp is the fixed and sessile form with mouth and tentacles facing upwards. It reproduces asexually by budding to form the second body form.
