Given below are two statements: Statement I - Gemmule is an internal bud formed in the body of coelenterate. Statement II - The amoebocytes of the gemmule form protective covering membrane on the outerside. In the light of above statements, choose the correct option given below:

Step-by-step solution

Statement I is incorrect because gemmules are internal buds formed for asexual reproduction in sponges (phylum Porifera), not in coelenterates. Coelenterates typically reproduce asexually through external budding. Statement II is incorrect because a gemmule consists of a central mass of totipotent cells called archaeocytes, which are responsible for developing into a new sponge. The protective outer covering (consisting of spongin and spicules) is secreted by the amoebocytes (specifically spongioblasts and sclerobl
