True
The paramecium swims by way of using a flagella.
False
Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself identify the major difference from the
list below.
Division of labor
,Why is it important to know the limitations of technology?
If the limits are known, advancements can occur
Why is it important to know the limitations of technology?
If the limits are known, advancements can occur and science can progress, if you don't know how technology works, you don't know
what data is being missed
DNA in extant prokaryotic cells is circular.
True
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
Fluorescence microscopy is a form of light microscopy.
True
After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is (pick the best order):
Filapodia, lamellipodia, cell muscle, retraction fiber.
Finish the sentence based on my lectures: The association of ribosomes with invaginations would support the
theory.
membrane, endomembrane
The cytoskeleton gave rise to the nuclear envelope.
False
Motility improved the fitness of these early cells because:
It allowed them to move away from predators and towards food.
In an extant prokaryotic cell, the outer boundary of life is the capsule.Term
False
A normal cell is and for growth.
mortal, Anchorage-dependent
The cytoskeleton enabled the primitive cell to become motile.
True
The ancient earth did not contain much oxygen.Term
True
When cancer cells are crowded by surrounding cells, the cancer cells become spherical and they can still go through cell division.
True
Cancer Cells are...
anchorage independent and immortal

True
List one limitation of the cell culture technique.
Has to be kept sterile
List one limitation of the cell culture technique.
1. Not all cells grow in culture2. Cells lose their histotype (in vivo shape) and 3-D structure of tissue is changed3. Metabolism likely
changes
, What limits how big a cell can be?
The surface area to volume ratio
TEM provides a thin, two-dimensional section of the object being studied.
True
Ribosomes bound to some of the membrane invaginations in the endomembrane theory.
True
Loss of the cell wall was required for the endomembrane system theory.Term
True
Loss of the cell wall is required for the endosymbiotic theory.
True
Active transport uses ATP to move components in parallel with their concentration gradient, that is: from a high concentration to a low
concentration.
False
The ER is contiguous with the nuclear envelope.
True
What are the two functions of a membrane?
Partition water, and compartmentalize enzymes to increase efficiency of chemical reactions
What are the two functions of a membrane
a barrier from water and compartmentalization
