Phylum Porifera (sponges) multicellular organisms without tissues, organs, or body cavity Heterotroph organism that obtains energy from the foods it consumes; also called a consumer Spicules hard spear or star-shaped structures; made of CaCO3 (limestone) or silica (glass) Choanocyte line the gastrovascular cavity & capture food Amoebocyte digest & distribute food Osculum large opening at the top where excess water leaves Spongocoel large central cavity of the sponge

WSU Biology 106 Exam 3 Questions Marking Scheme Spongocoel - ANSWER- the large central cavity of sponges. water enters the spongocoel through tiny pores called ostia and it exits through the large opening called the osculum. spongocoel is lined with choanocytes which help to create a current in the water. Spicule - ANSWER- structural elements found in most sponges. They provide structural support and deter predators. Large ones are called megascleres while microscopic ones are calle...
