Final Jeopardy
$100 Question from Microscopes
Why are microscopes used?
$100 Answer from Microscopes
To view organisms that are too
small to be seen; “microscopic”
$200 Question from Microscopes
Explain the correct way to hold a
microscope during transport.
$200 Answer from Microscopes
Place one hand under the base,
while the other hand grasps the
arm; hold the microscope close to
upper body
$300 Question from Microscope
What is the name of the structure that
contains the objective lenses, and allows
for the user to switch between them?
$300 Answer from Microscopes
Revolving Nosepiece
$400 Question from Microscopes
A
B
Name the
structures in
which arrows A
and B are pointing
to.
$400 Answer from Microscopes
A- Stage
B- Course Adjustment Knob
$500 Question from Microscopes
You are unable to locate the specimen when
using a microscope. Describe at least one
action that you might take to resolve this issue.
$500 Answer from Microscopes
1. Make sure that light is available (may need
to power “on” the microscope, adjust the
light source, or adjust the diaphragm)
2. Make sure that the low-power objective
lens is secured in place
$100 Question from Cells I
Cells that do not have a nucleus are
called______________ cells.
$100 Answer from Cells I
Prokaryotic
$200 Question from Cells I
This is a network of protein
filaments that provides shape
and structure for the cell, while
allowing for it to move
$200 Answer from Cells I
Cytoskeleton
A
$300 Question from Cells I
B
Provide the name
of each cell
organelle at
arrows A and B.
$300 Answer from Cells I
A. Golgi Apparatus
B. Nucleus
$400 Question from Cells I
Explain the role of the conjugation pili.
$400 Answer from Cells I
Found in prokaryotic cells; conjugation pili
attach to adjacent cells and allow for the
transfer of DNA
$500 Question from Cells I
List the 3 components of the Cell Theory
$500 Answer from Cells I
1. All living organisms are made of cells
2. Cells are the basic structural and
functional units of life
3. Cells come only from pre-existing cells
$100 Question from Cells II
This is the organelle responsible for
the production of cellular energy
$100 Answer from Cells II
Mitochondria
$200 Question from Cells II
Name the two locations where
ribosomes are found inside a
eukaryotic cell.
$200 Answer from Cells II
1. Free-floating in the cytoplasm
2. Attached to the Rough Endoplasmic
Reticulum
$300 Question from Cells II
List two differences
between a plant and an
animal cell.
$300 Answer from Cells II
Plant has a cell wall and chloroplasts, while
animal does not.
Animal has centrioles and lysosomes, while
plant does not.
$400 Question from Cells II
Describe the role of a lysosome in a
eukaryotic cell
$400 Answer from Cells II
Lysosomes contain enzymes which
are used to digest substances within
the cell (food, waste, etc.)
$500 Question from Cells II
Explain the difference between the
location of the DNA in prokaryotic
and eukaryotic cells.
$500 Answer from Cells II
Euk.-DNA is located within
the nucleus of the cell
Prok.-DNA is located in the
cytoplasm of the cell, in a
region referred to as the
nucleoid
$100 Question from Cell
Membrane
Where is the cell
membrane located?
$100 Answer from CM
Surrounding the cell; encases cytoplasm
$200 Question from CM
The cell membrane is “semipermeable.” Explain what this
means.
$200 Answer from CM
Semi-permeable refers to the fact
that only certain substances can
pass through the membrane
$300 Question from CM
The phospholipids within the cell
membrane are arranged so that their
_____________ heads face
outward.
$300 Answer from CM
Hydrophilic
$400 Question from CM
This is a structural component of the cell
which adds support and helps to maintain
the fluidity of the cell
Hint: Some is “good” and some is “bad”
$400 Answer from CM
Cholesterol
$500 Question from CM
The fluid mosaic model is often
used to describe the cell
membrane. Explain why the term
“mosaic” is used.
$500 Answer from CM
There are a variety of proteins of
different structure and function,
randomly positioned throughout the
cell membrane; similar to a mosaic
with a variety of glass/stone pieces
placed together to make an image.
$100 Question from Transport
Which type of transport
requires the use of energy?
$100 Answer from Transport
Active Transport
$200 Question from Transport
Describe the process of
diffusion?
$200 Answer from Transport
Solute molecules move from an area
of high concentration to an area of
low concentration until equilibrium
is reached.
$300 Question from Transport
The term used to describe
substances leaving the cell
following the fusion of a
vesicle to the cell membrane
$300 Answer from Transport
Exocytosis
$400 Question from Transport
Explain how osmosis would occur as a
result of a hypotonic environment.
$400 Answer from Transport
A hypotonic environment indicates that
there is less solute outside the cell than
inside, and therefore a higher
concentration of water outside the cell.
Therefore, water will flow into the cell,
causing it to swell.
$500 Question from Transport
Explain the process of endocytosis.
(What happens to the cell membrane).
$500 Answer from Transport
“Pockets” will be formed in the cell
membrane in order to surround the
substance. Eventually, the pocket
will close and break away from the
membrane, having formed a vesicle
(now floating in the cytoplasm of
the cell).
