ASU Bio 181 Exam 1
1n order to examine cells which are smaller than can be detected by the human senses
what needs to be used ? - ✔️✔️technology
Why did Motility improved the fitness of these early cells? - ✔️✔️it allowed them to
move away from predators and towards food
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
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
T/F In an extant prokaryotic cell the outer boundary of life is the capsule. - ✔️✔️false
T/F When cancer cells are crowded by surrounding cells, the cancer cells become
spherical and they can still go through cell division. - ✔️✔️true
The association of ribosomes with _____ invaginations would support the _____ theory.
- ✔️✔️membrane, endomembrane
T/F Loss of the cell wall was required for the endomembrane system theory. - ✔️✔️true
T/F Fluorescence microscopy is form of light microscopy - ✔️✔️true
T/F Loss of the cell wall is required for the endosymbiotic theory. - ✔️✔️true
T/F TEM provides a thin, two-dimensional section of the object being studied. -
✔️✔️true
T/F The sytoskeleton enabled the primitive cell to become motile. - ✔️✔️true
T/F the ancient earth did not contain much oxygen - ✔️✔️true
A normal cell is _____ and ____ for growth. - ✔️✔️mortal, anchorage dependent
T/F Ribosomes bound to some of the membrane invaginations in the endomembrane
theory - ✔️✔️true
T/F the cytoskeleton gave rise to the nuclear envelope - ✔️✔️false
, What limits how big a cell can be? - ✔️✔️the surface area to volume ratio
T/F DNA in extant prokaryotic cells is circular. - ✔️✔️True
T./F the end of the retraction fiber touching the cell culture plate still contains the cell
equivalent of super glue. - ✔️✔️true
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
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.
compared to bacteria which of the cell types below are not responsible for finding food?
- ✔️✔️lymphocyte, macrophage, and fibroblast
T/F In your own mulitcellular body, different cells in your body have a division of labor
between them. - ✔️✔️true
T/F The paramecium swims by way of using a flagella - ✔️✔️false
T/F A normal cell is anchorage-dependent for growth and mortal - ✔️✔️true
what limits the paramecium from acquiring more complex functions? - ✔️✔️cannot fit
anymore biomachinery into its space
comparing a singled cell eukaryotic organism with a multicellular organism such as
yourself identify the major difference from the list below. - ✔️✔️division of labor
in the cell biology what can limit the progress of science - ✔️✔️technology
T/F a cell that is anchorage-dependent for growth will also exhibit contact inhibiton. -
✔️✔️true
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.
T/F the contractile vacuole of the paramecium is possibly an evolutionary of the kidney -
✔️✔️true
