Which structures are found on sponges?
PSYCHO15rus [73]

Answer:

The special cells of the sponge include those that filter sea water; cells that are phagocytic (that engulf and digest food particles); those that form the external 'skin', breathing pores and tubes through which water enters and leaves the body; and those that secrete the mineral and organic skeletons, called spicules and fibres, respectively. Sponges are also unique because nearly all their cells can change function as required (totipotency).
