BIO 102 Module 2 Actual Exam Study Questions with 100% Correct Answers Already Graded A+ | Latest Version 1. How did the nucleus form? - ANSWER invagination 2. invagination - ANSWER plasma membrane folds in on itself and inner compartments (organelles) are formed 3. the job of the nucleus - ANSWER - protect DNA - control what goes in and out of the nucleus 4. example of flagellates - ANSWER euglena 5. flagellum - ANSWER a long "tail" used for movement 6. flagellates also use _______ to move - ANSWER cytoplasm 7. Are the 3 separate groups of protists monophyletic or polyphyletic? - ANSWER monophyletic 8. Protists can be grouped into.... - ANSWER Protozoans (animal-like protists) Slime molds (fungus-like protists) Algae and Seaweeds (plant-like protists) 9. protozoans (animal-like protists) - ANSWER - unicellular - heterotrophic - live in wet environments - most swim around hunting for prey - very active - reproduce through binary fission (asexually) 10. slime molds (fungus-like protists) - ANSWER - unicellular but form colonies - found in moist environments, but not aquatic ex. rotting wood - slowly move across surfaces eating microorganisms through phagocytosis 11. algae and seaweeds (plant-like protists) - ANSWER - unicellular OR multicellular - autotrophs - live in aquatic environments - primary producers 12. primary producers - ANSWER basis of the food chain; use sunlight to produce ATP 13. protists are very __________ - ANSWER diverse 14. parasite - ANSWER an organism that lives in or on another organism, that causes some damage to the host 15. disease caused by parasitic protists.... - ANSWER malaria 16. endoplasmic reticulum - ANSWER an organelle coming off of the nucleus where proteins are made 17. golgi apparatus - ANSWER newly synthesized proteins are given some final processing steps 18. lysosomes - ANSWER sac-like structure that contain enzymes that break down damaged molecules into things the cell may need 19. mitochondria - ANSWER powerhouse of the cell formed by endosymbiosis 20. endosymbiosis - ANSWER smaller prokaryotes formed close symbiotic relationships with larger prokaryotes and evolved into organelles 21. heterotrophic protists eat through __________ - ANSWER phagocytosis 22. phagocytosis - ANSWER process in which extensions of cytoplasm surround and engulf large particles and take them into the cell 23. some protists feed through ___________ - ANSWER absorption or the engulfing of food 24. water regulation - ANSWER protists need to expel water to maintain life 25. contractile vacuole - ANSWER membrane bound vacuole that pushes water out of the cell 26. example of ciliates - ANSWER paramecium 27. tiny hairs that line the outside of the cell and propel movement - ANSWER cilia 28. ciliates eat by ___________ - ANSWER phagocytosis 29. ciliates eating process - ANSWER cilia push food in the oral groove, then food becomes engulfed in the membranes and digested 30. example of sarcodines - ANSWER amoeba 31. sarcodines move by ________ - ANSWER oozing or pseudopodia 32. pseudopodia stretches and cytoplasm flows in, moving the cell forward 33. amoebas take in food by... - ANSWER pseudopodia extend to surround the food, then food becomes pinched off and trapped, where lysosomes can then release enzymes to break down the food 34. malaria is caused by protist parasites in the genus _____________ - ANSWER plasmodium
