                  Annotations:

                  • Polyp is dominant stage Made of colonies of polyps (each polyp serves a different purpose) zygote-planula-budding-polyp-budding medusa
                2. reproduction

                  Annotations:

                  • Usually asexual: polyp Sexual: medusa The two cycles share similar body plane- mesoglea (which is thicker in the medusa) Medusa contains the eggs and sperm to make the fertilized egg Planula is formed from zygote which eventually turns into a polyp
