Porifera

marine environment

• multicelluar
• lack true tissue
• suspension feeder

• cells in Porifera that have flagella that move water
• flagella beat and create current of water
• filters water -> food particles ingested by phagocytosis

• named for mode of locomotion
• help distribute food throughout sponge
• produce skeletal fibers (elastic or hardened)
• determine if sponge is soft or hard

Water -> Small pores in body wall -> Central cavity -> Exits out

water pulled in/ filtered by choanocytes
