Marine Bio Practice Test

Practice Test for my Marine Biology Students I’ll give you a phrase and you’ll give me the words that correspond. 1. A bloom of dinoflagellates that causes a toxic environment in the ocean. 2. A long, whiplike structure that a cell uses to move around. 3. A powder made of the skeletons of diatoms used for filter media and as a pesticide. 4. A word used to refer to the shells of the various Protista. 5. In an endosymbiotic relationship, the term for the organism which HOUSES the other. 6. In an endosymbiotic relationship, the term for the organism which lives in the other. 7. A symbiosis where both organisms benefit 8. A symbiosis where only one organism benefits but the other is not harmed. 9. A symbiosis where only one organism benefits but the other is harmed. 10.A rod shaped of a bacteria. 11.A corkscrew shape of a bacteria. 12.A round shape of a bacteria. 13.the kingdom the bacteria are in. 14.The kingdom the protista are in. 15.The cell wall of a plant cell is cellulose but a bacteria’s cell wall is made of this. 16. The toxic substance produced by diatoms. 17.The accumulation of radiolarians at the bottom of the ocean that is hundreds of meters thick. 18.The type of dinoflagellate that is commonly found as an endosymbiont in corals, anemones, clams, squids and other marine organisms. 19.The extensions of the radiolarian cell membrane that it uses to engulf prey. 20.The term that refers to a protist engulfing its prey item by extending cell membrane around the prey. 21.The term that refers to an organism that makes its own food. 22.The term that refers to an organism that must eat its own food. 23.A type of respiration that does not require oxygen. 24.An organism that MUST do aerobic respiration. 25.An organism that can do aerobic or anaerobic respiration. 26. An organism that MUST DO ANaerobic respiration. 27.The type of cell division found in bacteria. It is very similar to mitosis. 28.Some that stimulates a response in an organism. 29.The term that refers to an organism moving toward a stimulus; light, darkness, chemical attractants, etc. 30.A cell without a nucleus or membrane covered organelles. 31.A cell with a nucleus and membrane covered organelles. 32.The term which refers to organisms that are subject to ocean currents and can be as small as microscopic organisms up to the size of very large fish.

Diatoms______Dinoflagellates_____Radiolarians______ Foraminifera ______ Short ANSWER 46.Many organisms such as corals and anemones are not photosynthetic but because of endosymbiosis, they are. Explain this. 47.Select one of the protista and discuss their ecological/economic importance in detail. !!!!!!!!!!!!!!!!!USE THE QUALITIES OF A GOOD ANSWER!!!!!!!!!!!
