Question

What do choanocytes do in sponges?

Answer 1

1. Sponges: They are invertebrate organisms belonging to the Class Porifera.
2. They are ammonotelic creatures because they secrete nitrogenous waste as ammonia.
3. Choanocytes are the spongocoel's collar cells.
4. The steady beating of flagella in choanocytes aids in water pumping and nutrient absorption by filtering them from water.
5. Thus, they play a major role in obtaining nutrition and excreting the waste materials within the flow of water regulated by the flagella of choanocytes.
