Question

Quizplus · Accepted Answer

Spicules are the skeletal elements that give support to a sponge's body. Spongin is a protein that can also provide support, but it is not a skeletal element. Choanocytes and collar cells are cells that line the inside of a sponge's body and are involved in feeding and circulation. Porocytes are cells that make up the pores through which water enters the sponge's body.
