ASU BIO 181 MODULE 1 EXAM COMPLETED 2023 GRADED A+ ASU Bio 181 Exam 1 1. The association of ribosomes with _____ invaginations would support the _____ theory.: membrane, endomembrane 2. After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is?: filapodia, lamellipodia, cell muscle, retraction fiber 3. T/F It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells.: true 4. T/F In an extant prokaryotic cell the outer boundary of life is the capsule.- : false 5. T/F When cancer cells are crowded by surrounding cells, the cancer cells become spherical and they can still go through cell division.: true 6. T/F Loss of the cell wall was required for the endomembrane system theory.: true 7. T/F Fluorescence microscopy is form of light microscopy: true 8. T/F Loss of the cell wall is required for the endosymbiotic theory.: true 9. T/F TEM provides a thin, two-dimensional section of the object being studied.: true 10. T/F The sytoskeleton enabled the primitive cell to become motile.: true 11. T/F the ancient earth did not contain much oxygen: true 12. A normal cell is _____ and ____ for growth.: mortal, anchorage dependent 13. T/F Ribosomes bound to some of the membrane invaginations in the endomembrane theory: true 14. T/F the cytoskeleton gave rise to the nuclear envelope: false 15. What limits how big a cell can be?: the surface area to volume ratio 16. T/F DNA in extant prokaryotic cells is circular.: True 17. Why did Motility improved the fitness of these early cells?: it allowed them to move away from predators and towards food 18. T./F the end of the retraction fiber touching the cell culture plate still contains the cell equivalent of super glue.: true 19. T/F the presumed first step in the transition of the primitive, proto-prokaryotic cell into the primitive, proto-eukaryotic cell was the loss of the cell wall.: true 20. 1n order to examine cells which are smaller than can be detected by the human senses what needs to be used ?: technology 1 / 6 ASU Bio 181 Exam 1 21. A cell that is itself an organism must have a minimum of four needs presented in lecture: find food, find shelter, find mate, and reproduce. 22. compared to bacteria which of the cell types below are not responsible for finding food?: lymphocyte, macrophage, and fibroblast 23. T/F In your own mulitcellular body, different cells in your body have a division of labor between them.: true 24. T/F The paramecium swims by way of using a flagella: false 25. T/F A normal cell is anchorage-dependent for growth and mortal: true 26. what limits the paramecium from acquiring more complex functions?: - cannot fit anymore biomachinery into its space 27. comparing a singled cell eukaryotic organism with a multicellular organism such as yourself identify the major difference from the list below.: division of labor 28. in the cell biology what can limit the progress of science: technology 29. T/F a cell that is anchorage-dependent for growth will also exhibit contact inhibiton.: true 30. explain what limits an individual cell from becoming more complex: - individual cell have a limit number of biomolecular machines. In a multicellular organism you get a division of labor between different cell types so that the whole can do more than the sum of the parts with similar number of biomolecular machines per cell. 31. T/F the contractile vacuole of the paramecium is possibly an evolutionary of the kidney: true 32. a singled celled eukaryotic organism: has a limited number of biomolecular machines must find food, shelter, a mate and reproduce escape from predators 33. the paramecium discussed in class contained an organelle the contractile vacuole. this is the presumed precursor of the:: kidney 34. T/F in your own multicellular body, cell wit
