1. Phylum Porifera - Answer-- sponges - loosely organized and lack tissues - multicellular with several types of cells - 8,000 species, mostly marine - no apparent symmetry - adults sessile, larvae free-swimming - water drawn through pores into spongocoel - flows out through osculum - choanocytes line spongocoel - mesohyl between choanocytes and epithelial cells - reproduce sexually and asexually 10. Phylum Nematoda - Answer-- roundwomrs - in nearly all habitats - over 20,000 specie...
