Question

Digestion of food is completed in sponges in

• A. Choanocytes
• B. Trophocytes
• C. Thesocytes
• D. Phagocytes

Answer 1

The correct option is B Trophocytes

A. Choanocytes, also called as collar cells, are the specialised flagellated cells that form the gastral epidermis of the inner layer of body wall in sponges

B. Trophocytes are the cells in which digestion of food takes place. These cells are also called as nurse cells.

C. Thesocytes are the storage cells with food reserve and have lobose (i.e. bulbous, thick) pseudopodia.

D. Phagocytes are the cells that ingest the food particles and thus, are meant for feeding.

Hence, digestion of food is completed in sponges in trophocytes. So, the correct answer is 'Trophocytes'.
