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:
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:
Options
- ABoth statement I and statement II are correct.
- BBoth statement I and statement II are incorrect.
- CStatement I is correct but statement II is incorrect.
- DStatement I is incorrect but statement II is correct.
Correct answer
B. Both statement I and statement II are incorrect.
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 scleroblasts) of the parent sponge's mesohyl, not by cells belonging to the gemmule itself. The gemmule does not contain amoebocytes.
Therefore, both Statement I and Statement II are incorrect.
Answer: Both statement I and statement II are incorrect.
