Cells Review
Which statement explains why
viruses are exceptions to the cell
theory?
1.
2.
3.
4.
They contain genetic material.
They are not made up of cells.
They reproduce by mitosis.
They are surrounded by a protein
coat.
Give the cell organelle that
performs each function.
1. Transport materials throughout
the cell = Endoplasmic reticulum
2. Protein production = ribosomes
3. Digests food = lysosomes
4. Regulates what enters and leaves
the cell = cell membrane
5. Produces energy = mitochondria
6. Controls all cell activities = nucleus
7. Holds cell organelles = cytoplasm
8. Site of photosynthesis = chloroplasts
9. Used in cell division = centrioles
10. Gives plant cell
shape and support = cell wall
11. Destroys old cell parts = lysosomes
12. Packages materials = golgi bodies
Identify some differences between
prokaryotic and eukaryotic cells.
Prokaryotic
no nucleus
Eukaryotic
nucleus
no membrane
bound organelles
have membrane
bound organelles
smaller
DNA is found in
cytoplasm
larger
DNA is found inside
the nucleus
1. What type of transport does this
picture represent?
active transport
2. Explain your answer.
Substances are moving from a
LOW to HIGH concentration.
The diagram above shows the same type of
molecule in area A and area B. With
the passage of time, some molecules move
from area A to area B. This movement is
the result of the process of ____.
passive transport
C6H12O6 + 6O2
 6CO2 + 6 H2O + X
1. What is the name of the process
represented above?
aerobic respiration
2. Where does this process occur?
mitochondria
3. What molecule does X represent?
36 ATP
C6H12O6  CO2 + alcohol + X
1. What type of respiration is represented
above? anaerobic respiration
2. What is the specific name for this
process? alcoholic fermentation
3. Where IN A CELL does this process
occur? cytoplasm
4. What type of cell carries on this
process? Yeast cells
4. What molecule does X represent? 2 ATP
C6H12O6  lactic acid + X
1. What type of respiration is represented
above? anaerobic respiration
2. What is the specific name for this
process? lactic acid fermentation
3. Where IN A CELL does this process
occur? cytoplasm
4. What type of cell carries on this
process? Muscle cells
5. What molecule does X represent? 2 ATP
Identify some differences between
passive and active transport.
Passive transport Active transport
Substances move
from high to low
No energy needed
Diffusion and osmosis
Substances move
from low to high
Needs energy
pinocytosis and
phagocytosis
