USABO Biosystematics Final Exam Questions 2024. Calcarea, Silicea (sponges) - ANSWER Lack true tissues; have choanocytes (collar cells-flagellated cells that ingest bacteria and tiny food particles) Cnidaria (hydras, jellies, sea anemones, corals) - ANSWER Unique stinging structures (nematocysts) housed in special cells (cnidocytes); diploblastic, radially symmetrical, gastrovascular cavity Plathyhelminthes - ANSWER Dorsoventrally flattened, unsegmented acoelomates; gastrovascular cavity ...

Characteristics of an Animal - Answer- heterotroph (eat other organisms for food), multicellular (no cell wall, eukaryotic), motility/movement, *neurons/muscle cells (except sponges) Surface Area to Volume Ratio - Answer- limits the size of cells, as surface area increases volume decreases Importance of Surface Area - Answer- determines rate at which nutrients diffuse across a membrane into a cell and rate at which waste products diffuse out of cells Techniques Animals use to Increase S...

Bio II Final Practical. Pseudocoelomates - coelom is derived from both the endoderm and the mesoderm ie. rotifers and roundworms (hookworms) Eucoelomates - True coelomates - derived from only mesodermal tissues. [27] Phylum Porifera - -sponge -Multicellular; no tissues/organs -can vary from radially symmetrical to irregularly shaped.
