Answer:

Sponges belong to phylum Porifera because they have perforated body and water transport or canal system. Water enters through minute pores (ostia) in the body wall into a central cavity, spongocoel, from where it goes out through the osculum. This pathway of water transport is helpful in food gathering, respiratory exchange, and removal of waste. Perforations are due to ostia in the body of sponges.
