Question

Which of the following cell type is capable of giving rise to other cell types in sponges?

• A. Pinacocytes
• B. Thesocytes
• C. Archaeocytes
• D. Collencytes

Answer 1

Answer: (C)

Archaeocytes

Sponges have cellular grade organization, they don't have organs like higher organisms, instead, have specialized cells such as Pinacocytes (skin cells) that line the exterior sponge body wall. Archeocytes are important, they are totipotent and can change into all other types of sponge cells. The collencytes, found in the mesohyl, secrete fibers and often form a net in the cytoplasm. Thesocytes are responsible for intracellular digestion along with choanocytes in sponges.

So, the correct answer is option C.
