41 - 43. What is the Cell Theory? (3 parts)
44. – 45. What is a prokaryotic cell (i.e. what special things does it have or not have?)
Give at least 1 example of a prokaryotic cell.
46. – 47. What is a eukaryotic cell (i.e. what special things does it have or not have?)
Give at least 1 example of a eukaryotic cell.
48. – 49. The cell membrane is called a “fluid mosaic.” Explain the structure of the
cell membrane and how it is a fluid mosaic. Drawing a picture might help, but
is not necessary.

Pretest: Ch 7 Cell Structure and Function
Label the diagram below by filling in the table with the name of each organelle
indicated and its function/job within the cell
Letter: Name of structure:
Function/job of structure:
A
Cytoplasm
Dissolved materials, “fills in”
B
Chloroplast
C
Nuclear
membrane
Nucleus
D
E
F
cell
Photosynthesis; makes energy
for plants
Controls in/out of nucleus
Controls cell functions, contains
DNA/chromosomes
Endoplasmic Makes/packages materials (fats
reticulum
and proteins) for transport inside
cell
Ribosome
Make proteins
G
H
I
J
K
L
Golgi
Apparatus
Central
Vacuole
Lysosome
Cell
membrane
Mitochondria
Cell Wall
Modifies proteins/materials from
ER for use outside or inside cell
Stores water for plant cell
Holds digestive enzymes
Controls what goes into and out
of cell
makes energy (ATP) for cell
functions; cell respiration
Support/structure for plant cells
25. Which cell above is a plant cell and which is an animal cell? How can you tell
(what unique characteristics does each have)?
Cell 1 …animal…has no central vacuole, no cell wall,
no chloroplasts
Cell 2…plant… has central vacuole, cell wall,
chloroplasts
26. What is the Cell Theory?
3 parts:
 All living things made of cells
 Cells are basic structure and function of living
things (can do all things living things can do)
 Cells only come from other cells
27. What is a prokaryotic cell (i.e. what special things does it have or not have?) Give
at least 1 example of a prokaryotic cell.
Simpler (older) form of life, like bacteria
No membrane-bound organelles…no lysosomes,
vacuoles, nucleus, mitochondria, golgi bodies,
endoplasmic reticulum, etc. All cell functions take
place in the cytoplasm rather than in specific
organelles.
28. What is a eukaryotic cell (i.e. what special things does it have or not have?) Give
at least 1 example of a eukaryotic cell.
More complex forms of life (plants, animals, fungi,
protists)
Have membrane-bound organelles…lysosomes,
vacuoles, nucleus, mitochondria, golgi bodies,
endoplasmic reticulum, etc. All cell functions take
place in specific organelles.
29. – 30. The cell membrane is called a “fluid mosaic.” Explain the structure of the
cell membrane and how it is a fluid mosaic. Drawing a picture might help, but
is not necessary.
Phospholipid bilayer…2 layers of molecules called
phospholipids (fats with a phosphate group).
Phosphate group is on outside/inside of cell, fats are
between…within the membrane itself.
Then there are large proteins/carbohydrates
embedded (mosaic) in this that are free to move
around (fluid). The proteins/carbohydrates mark the
cell, and help the cell perform its functions and help
move things into and out of the cell.
