1 Marine Biology Worksheet II: Selected Answers Invertebrates and Algae
2 Chapter 4: Taxonomy Section at End 1. What are some differences between Kingdom(Domain) Bacteria and Kingdom (Domain) Archaea? Prokaryotic bacteria were separated into these two Kingdoms (Domains) recently when new techniques to analyze DNA showed that there were two groups pr prokaryotic bacteria that differed significantly in their genetic composition. Kingdom (Domain) Archaea were originally thought to be extremophiles - lovers of extreme environments such as hot springs and hydrothermal vents. However, new sampling techniques have shown Archaea to be very common in the marine environment. Kingdom (Domain) Bacteria includes common bacteria including species that cause strep throat and staph infections. 2. Plant and animals are in Domain Eukarya. How do the cells of plants and animals differ from the cells of organisms in Domain Bacteria and Domain Archaea? The cells of organisms in Domain Eukarya have a membrane bound nucleus and have membrane bound cellular organelles. Organisms in Domain Bacteria and Domain Archaea are prokaryotic. That means that their cells lack a nucleus. 3. Define the term Biological Species. What are some of the problems with this species definition? If two organisms belong to the same species they must be able to interbreed and produce fertile offspring. This definition is not useful if one is studying single celled organisms that reproduce asexually by simple cell division. This definition is not useful if one is a palaeontologist that studies fossils. 4. List the 7 taxonomic ranks form in order stating with Kingdom and ending with species. Kingdom P C O F G Species 2
3 Chapter 5: The Microbial World 5. Define the term detritus: 6. What role do decay bacteria play in marine ecosystems? 7. Can cyanobacteria be considered primary producers? Explain. 8. What are stromatolites? 9. Photosynthetic bacteria use light as an energy source. What do chemosynthetic bacteria use as an energy source? 10 What is meant by the term nitrogen fixation? Give an example of a group of organisms that are capable of fixing nitrogen. 11. Describe the difference between the terms plankton and nekton. (See glossary in text) Plankton Nekton 12. Describe the difference between the terms phytoplankton and zooplankton. (See glossary in text) Phytoplankton Zooplankton 3
4 13. Diatoms and Dinoflagellates belong to Kingdom. Describe at least two differences between diatoms and dinoflagellates. Diatoms Dinoflagellates Silica or glass shell Outer covering is cellulose Maintains position close to Maintains position close to surface with surface with an oil filled flagella vacuole. Both organisms are found in surface waters since they need light for photosynthesis Both organisms are components of phytoplankton 14. Foraminiferans and Radiolarians are in Kingdom. Describe at least two differences between foraminiferans and radiolarians. Foraminiferans Radiolarians Shell is composed of limestone (Calcium carbonate) Most species of foraminiferans live on the bottom Shell is composed of silica dioxide (glass) Radiolarians are planktonic 15. What does the term bioluminescence mean? Give an example of an organism that is bioluminescent. 16. What are red tides? Massive blooms of phytoplankton. The organisms that cause red tides include dinoflagellates. Since only about half the organisms that are known to cause red tides are dinoflagellates a better name for red tides is Harmful Agal Blooms (HAB s). 17. What are zooxanthellae and why are they important to coral reefs? Zooxanthellae are dinoflagellates (phytoplankton) that live inside the tissues of corals in a symbiotic relationship known as mutualism. This is a relationship where both organisms benefit by living together. The coral is a carnivore that grows in nutrient poor waters. Nitrogen is a major limiting factor for phytoplankton growth in nutrient poor waters. The coral supplies the dinoflagellate with nitrogenous waste products from protein metabolism. (Remember carnivores eat meat which is protein). The dinoflagellate(zooxanthellae) are capable of photosynthesis and feed the coral glucose which enables it to grow faster than would be possible without the zooxanthellae. Corals expel their zooxanthellae when they are stressed. This phenomenon is called coral bleaching. 4
5 Chapter 7: Marine Animals without a Backbone 25. Discuss the functions of each of the following cell types or structures in Porifera A. Collar cells or choanocytes These are the filter feeding cells of a sponge. B. Osculum The opening through which water exits the sponge C. Ostium The opening through which water enters the sponge D. Spongin The protein fibers that make up the skeleton of a bath sponge E. Spicuoles The structures that make up the skeleton of most sponges. They may be composed of calcium carbonate (limestone) or silica dioxide (glass) F. Pinacocytes The thin flat cells that cover the surface of a sponge 5
6 26. Sponges belong to Kingdom Phylum 27. Identify A through G on the diagram below : A. Osculum B. Pinacocytes C. Spongocoel D. Ostium E. Spicule F. Choanocyte G. Porifera 6
7 28. List 4 characteristics of Phylum Cnidaria. A. Have specialized stinging cells called cnidocytes that house a harpoon-like apparatus called a nematocyst B. They are diploblastic which means they have two embryonic tissue layers. The Ectoderm, which develops into the epidermis and the endoderm which develops into the gastrodermis. C. The have an incomplete digestive tract. Food enters the mouth and poop exits the mouth. D. Most cnidarians are dimorphic. This means that they have two body forms in their life history; a planktonic medusa stage and a sessile polyp stage. 29. Discuss the relationship between cnidocytes and nematocycts. 30. Describe the difference between the terms Filter Feeder and Deposit Feeder. Filter Feeder Deposit Feeder 31. Give an example of a organism with: A. Radial Symmetry B. Bilateral Symmetry 32. Give two examples of Siphonophores. What class in Phylum Cnidaria do Siphonophores belong to? A siphonophore is a colony of polyps. This means that a number of polyp individuals live together and function as one organism. The Portugese man-of-war (Physalia) and the bythe-wind sailor (Vellela) are both examples of siphonophores. 33. Give an example of an organism in Class Scyphozoa. How do organisms in Class Scyphozoa differ from organisms in Class Anthozoa? 7
8 34. Name two types of organisms in Phylum Cnidaria Class Anthozoa. 35. What are the three classes in Phylum Cnidaria? How are these classes distinguished from each other? Class Hydrozoa Class Scyphozoa Class Anthozoa Polyp stage emphasized Medusa stage emphasized Polyp stage only Medusa reduced Polyp stage reduced No medusa stage Siphonophores The moon jelly Corals and sea anemones Gonionemus Obelia 36. What is the difference between A and B on the diagram below. A. Cnidocyte with discharged nematocyst B. Cnidocyte with undischarged nematocyst C. The cells represented by drawing A and B are called? Cnidocytes 38. The simplest animals that have bilateral symmetry belong to Phylum Platyhelminthes 39. Organisms the swim using 8 rows of ciliary combs belong to Phylum Ctenophora 40. The segmented worms belong to Phylum Annelida 41. Almost all marine annelids belong to Class Polychaeta 42. The group of marine worms that lacks a body cavity belongs to Phylum Platyhelminthes 43. Describe the difference between the terms Diploblastic and Triploblastic. Diploblastic Triploblastic Two embryonic tissues layers Three embryonic tissue layers Ectoderm Ectoderm Endoderm Endoderm Mesoderm - between the ectoderm and Endoderm 8
9 44. What is the only group of organisms within Phylum Mollusca that has a closed circulatory system? Why is a closed circulatory system as well as well developed sense organs necessary in this group? Class Cephalopoda. This class includes the squid, octopus, nautilus, and the cuttlefish. The organisms in this class are predators. To be a good predator you need to be able to find your prey and catch you prey. Cephalopods have a well developed nervous system that allows them to see well, move fast, and have fine tuned muscular movement. They also have a closed circulatory system. This means that their blood is enclosed in blood vessels which enables them to transport blood quickly and efficiently to their muscles. Remember that blood carries oxygen and the mitochondria in muscle cells needs oxygen to make ATP. ATP fuels muscle contraction. Thus a closed circulatory system enables them to move fast. 9
