Question

Quizplus · Accepted Answer

The choanocyte is the closest to the cnidocyte, as both are involved in food capture. Choanocytes have a flagellum surrounded by a collar of microvilli that trap and engulf food particles, similar to how cnidocytes use nematocysts to capture prey. Amoebocytes are involved in transport and digestion, while epidermal and pore cells are involved in the maintenance and protection of the sponge.
