Unit 4: Microscopes, Structure and Function of Cells
Name ______________________________ Date __________________
Prokaryotes vs. Eukaryotes
Directions: Use your class notes and reading notes to complete the chart below.
Prokaryotes
Eukaryotes
Range of cell size in
Micrometers
Does this type of cell have
a nucleus (yes or no)
List the organelles
contained within this cell
type that are considered
Membrane-bound
Which Kingdoms are
represented by this cell
type?
Thought Questions:
1. Taking into consideration the differences in size and structures between
prokaryotic cells and eukaryotic cells. Which cell type do you think evolved
first on earth? Explain your guess.
2. The cells of multicellular organisms are eukaryotic. Multicellularity involves a
coordination of effort between cells. Which kingdoms mentioned above would
NOT have multicellular members? Explain your reasoning.
Prokaryotic Cells
Directions: Examine the labeled prokaryotic cell (bacteria). State the function of the labeled
structures. Match the structure with its function below
1. _____ Capsule
2. _____ Cell Wall
3. _____ Cytoplasm
4. _____ Flagella
5. _____ Nucleoid
6. _____ Pili
7. _____ Plasma membrane
a. This is the outer boundary of a
bacteria (prokaryote). It provides
structure and support.
b. This is the area in the cytoplasm that
contains the chromosome (DNA)
c. This is the only membrane that the
bacteria (prokaryote) is allowed to
have. It lies just inside the cell wall.
d. This is the fluid- like substance and
area that is surrounded by the cell
membrane (aka plasma membrane).
Ribosomes and nucleoid region are
found inside.
e. These are cytoplasmic extensions
that are used to grip onto surfaces
and to communicate with other
bacteria (prokaryotes)
f.
8. _____ Ribosome
This is a long, whip like structure
that is used for movement.
g. This is a protective coating that
covers the cell wall. Bacteria
secrete these when conditions are
harsh or when they are dormant.
h. These organelles DO NOT HAVE A
MEMBRANE. These organelles are
the site of protein synthesis. (where
proteins are made)
