A
mitochondrion
B
DNA
C
nucleus
D
cell
2) Which cell structure serves the stated function in both eukaryotic and prokaryotic cells?
A
DNA: surrounds cell contents

nucleus: stores genetic material
3) A chemical has been found to harm the same components in both prokaryotic and eukaryotic cells. Which components are those?
A
DNA, cytoplasm, ribosomes, and nucleus
B
DNA, cell membrane, ribosomes, and membrane-bound organelles
C
DNA, cell membrane, cytoplasm, and ribosomes
D
DNA, cell membrane, cytoplasm, and membrane-bound organelles
4) A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified?
A
The cell is prokaryotic because it contains mitochondria.
B
The cell is eukaryotic because it contains ribosomes.
C
The cell is eukaryotic because it contains mitochondria.
D
The cell is prokaryotic because it contains ribosomes.
5) Which organisms are prokaryotes?
A
plants
B
fungi
C
archaea
D
protists
6) Which statement is most likely to apply to a cell that has DNA within its cytoplasm?
A
It lacks ribosomes.
B
It has membrane-bound organelles.
C
It is multicellular.
D
It performs all functions for the organism.
7) A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the cell could be classified?
A
The cell is prokaryotic because it has cytoplasm.
B
The cell is prokaryotic because it has DNA.
C
The cell is eukaryotic because it has chloroplasts.
D
The cell is eukaryotic because it has a cell membrane.
8) The endosymbiotic theory helps to explain the origin of which structures?
A
mitochondria
B
nuclei
C
ribosomes
D
cell membranes
9) What observation led researchers to propose that chloroplasts evolved from cyanobacteria?
A
Both contain mitochondria.
B
Both perform photosynthesis.
C
Both produce proteins.
D
Both provide structure to cells.
10) The endosymbiotic theory provides an explanation for the origin of chloroplasts. Which trait of chloroplasts supports this explanation?
A
Chloroplasts rely on proteins that are made by the cell.
B
Chloroplasts are larger than prokaryotic cells.
C
Chloroplasts do not reproduce.
D
Chloroplasts have their own DNA.
