QUESTIONS WITH FULL SOLUTION
◉ After a cell is pancake shaped in a cell culture dish, the order of
events that occurs as a cell walks is?
Answer: 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.
Answer: true
◉ T/F In an extant prokaryotic cell the outer boundary of life is the
capsule.
Answer: false
◉ T/F When cancer cells are crowded by surrounding cells, the
cancer cells become spherical and they can still go through cell
division.
Answer: true
,◉ T/F Loss of the cell wall was required for the endomembrane
system theory.
Answer: true
◉ T/F Fluorescence microscopy is form of light microscopy
Answer: true
◉ T/F Loss of the cell wall is required for the endosymbiotic theory.
Answer: true
◉ T/F TEM provides a thin, two-dimensional section of the object
being studied.
Answer: true
◉ T/F The sytoskeleton enabled the primitive cell to become motile.
Answer: true
◉ T/F the ancient earth did not contain much oxygen
Answer: true
◉ A normal cell is _____ and ____ for growth.
Answer: mortal, anchorage dependent
, ◉ T/F Ribosomes bound to some of the membrane invaginations in
the endomembrane theory
Answer: true
◉ T/F the cytoskeleton gave rise to the nuclear envelope
Answer: false
◉ What limits how big a cell can be?
Answer: the surface area to volume ratio
◉ T/F DNA in extant prokaryotic cells is circular.
Answer: True
◉ Why did Motility improved the fitness of these early cells?
Answer: it allowed them to move away from predators and towards
food
◉ T./F the end of the retraction fiber touching the cell culture plate
still contains the cell equivalent of super glue.
Answer: true
