Question

Quizplus · Accepted Answer

Choanocytes, also known as collar cells, are flagellated cells that line the internal chambers of sponges and create water currents. They trap and ingest food particles, as well as exchange gases and remove waste products. Amoebocytes are another type of cell in sponges that function in digestion, reproduction, and the secretion of skeletal elements like spicules and spongin. Spicules and spongin are structural components of the sponge's body, providing support and protection. However, none of these are responsible for creating water currents.
