Label the following parts with the word bank below. Be careful with spelling and do not use capital letters. ostia (3) asconoidosculum (3) syconoidspongocoel leuconoid asconoid leuconoid ostia osculum ostia osculum ostia osculum spongocoel syconoid Porifera Vocab Matching Can you match the correct vocabulary word with its definition? Click on the button of a definition and drag the line that is created to its definition. Ostia location where water, food, and oxygen enter Osculum location where carbon dioxide and waste leave the sponge Spongocoel the central cavity of sponges Mesohyl connective tissue glue of sponges Spicules part of the sponge skeleton that keep the sponge open; calcareous or silica structures Spongin specialized collagen found in most sponges Can you correctly sort the characteristics into the correct canal type? Click on each of the labels and a drop-down menu will appear. From that menu select the correct canal system that it belongs to. Asconoid Flagellated Spongocoel Least Efficient Choanocytes are located in the spongocoel Smallest sponges Syconoid Flagellated Canals Medium Efficiency Choanocytes located in canals Evolved directly from Asconoid sponges Leuconoid Flagellated Chambers Most Efficient Choanocytes located in chambers Largest sponges Can you label the components of a sponge? Click on the blue dot and enter the name of the structure in the text box that appears. Use the words below to fill in the blank. Make sure that you spell it correctly!! DO NOT USE CAPITAL LETTERS!!!osculum ostia choanocyte spongocoel pinacocytesmesohyl amoebocyte spicule flagella osculum choanocyte ostia spongocoel pinacocytes mesohyl amoebocyte spicule flagella Can you sort the description or characteristic to the appropriate sponge structure? Click on the labels that represent a characteristic or a description. Select the appropriate sponge structure that is represented. Pinacocytes Protect the sponge Acts as the epidermis of a sponge Helps to regulate water flow Able to expand and contract Located lining the outside of the sponge Thin, flat cells Choanocytes AKA collar cells contain flagella creates water current able to trap food located with part of their structure glued in the mesohyl the other part in a canal or chamber location of where this cell type is determines its canal system circulates water Amoebocytes AKA Archaeocytes digests food able to wander around the mesohyl can change into other cell types the cell type found inside a gemmule no distinct shape; can change shape
