Pseudocoelomates - Study guides, Class notes & Summaries

Calcarea, Silicea (sponges) : Lack true tissues; have choanocytes (collar cells-flagellated cells that ingest bacteria and tiny food particles) Cnidaria (hydras, jellies, sea anemones, corals) : Unique stinging structures (nematocysts) housed in special cells (cnidocytes); diploblastic, radially symmetrical, gastrovascular cavity Plathyhelminthes : Dorsoventrally flattened, unsegmented acoelomates; gastrovascular cavity or no digestive tract Rotifera (rotifers) : Pseudocoelomates wi...

Muscle cells 2. Pseudopodia ...

What does "d" represent in the figure showing vessels and organs of the lymphatic system? The thymus gland What are the structures in plants that are responsible for taking in carbon dioxide? the leaves What two structures function in gas exchange? stomata and lenticels Which of the following is a service provided by fungi for human benefit? antibiotics What correctly describes the movements of actin and myosin fibers? When ADP and P come off myosin, the crossbridges move the actin fi...

Apoplastic route ▪ Through cell walls and extracellular spaces Symplastic route ▪ Through the cytosol Transmembrane route ▪ Across cell walls - ANSWER name and describe the three routes of transport within a plant Membrane potential is established through pumping H+ by proton pumps (Animals - movement of Na+ by Na+ K+ pumps) - ANSWER Explain how membrane potential is established in plant plasma membranes -active transport and passive transport -osmosis - ANSWER Describe the...

A) amoebocytes B) choanocytes C) mesohyl cells D) pore cells (porocytes) E) epidermal cells Answer: B 9) A radially symmetrical animal that has two embryonic tissue layers belongs to which phylum? A) Porifera B) Cnidaria C) Platyhelminthes D) Nematoda E) Echinodermata Answer: B 10) All of the following are characteristics of the phylum Cnidaria except A) a gastrovascular cavity. B...

Detailed yet concise lecture notes covering the content from the first lecture of invertebrate zoology. These first class notes are easy to read, understand and learn from - with helpful diagrams. Topics are covered thoroughly including: - Bilateral and radial symmetry (with diagrams) - Body cavities (coelomates, pseudocoelomates and acoelomates - examples and diagrams) - Porifera (choanocytes) - Eumetazoa (groups of cnidaria, life cycles, body structures)

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.
