What limits how big a cell can be?
A. Color
B. Wavelength
C. The surface area to volume ratio
D. Resolution
E. Type of electron microscopy. ---------CORRECT ANSWER-----------------The surface
area to volume ratio.
TEM provides a thin, two-dimensional section of the object being studied. ---------
CORRECT ANSWER-----------------TRUE
In an extant prokaryotic cell, the outer boundary of life is the capsule. ---------
CORRECT ANSWER-----------------FALSE
The ancient earth did not contain much oxygen. ---------CORRECT ANSWER-----------
------TRUE
,Why is it important to know the limitations of technology? ---------CORRECT
ANSWER-----------------Unable to view live cells under SEM magnification,
Microscopy is limited with magnification.
DNA in extant prokaryotic cells is circular. ---------CORRECT ANSWER-----------------
TRUE
Loss of the cell wall is required for the endosymbiotic theory. ---------CORRECT
ANSWER-----------------TRUE
The cytoskeleton gave rise to the nuclear envelope. ---------CORRECT ANSWER------
-----------FALSE
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.
Group of answer choices ---------CORRECT ANSWER-----------------FALSE
List one limitation of the cell culture technique. ---------CORRECT ANSWER-----------
-------Not all cells grow in culture
, -Cells lose their histotype (in vivo shape) and 3-D structure of tissue is changed
-Metabolism likely changes
It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes
to remove oxygen, which was toxic to the primitive cells. ---------CORRECT
ANSWER-----------------TRUE
A normal cell is ____________and _________________for growth. ---------
CORRECT ANSWER-----------------Mortal
Anchorage-dependant
Motility improved the fitness of these early cells because:
It allowed them to make a nuclear envelope.
It caused them to acquire ribosomes.
It allowed them to move away from predators and towards food.
Two of the above.
None of the above. ---------CORRECT ANSWER-----------------It allowed them to
move away from predators and towards food
Loss of the cell wall was required for the endomembrane system theory.
Group of answer choices ---------CORRECT ANSWER-----------------TRUE
