The internal buds are known as which of the following:
Correct answer: C. Gemmules
- A. Spicules
- B. Choanocytes
- C. Gemmules
- D. Both Options A and B are correct
Explanation
Spicules are the structural components of a sponge, or the "bricks," and the shapes, sizes, and composition are unique for each species.Choanocytes are the flagellated cell with a collar of protoplasm at the base of the flagellum, numbers of which line the internal chambers of sponges.Gemmules are a tough-coated dormant cluster of embryonic cells produced by a freshwater sponge for development in more favourable conditions.Therefore, option C is right choice here.
