Unit 1 – Concept 3 Prokaryote & Eukaryote
And Concept 4 Viruses
SB1A. Explain the role of cell organelles for both prokaryotic and eukaryotic cells,
including the cell membrane, in maintaining homeostasis and cell reproduction.
SB3D. Compare and contrast viruses with living organisms.

as quickly. Which of the following statements best explains this difference?
A. Eukaryotic cells are smaller than prokaryotic cells.
B. Eukaryotic cells have less DNA than prokaryotic cells.
C. Eukaryotic cells have more cell walls than prokaryotic cells.
D. Eukaryotic cells are more structurally complex than prokaryotic cells.
2. How are prokaryotic and eukaryotic cells similar?
A. Both contain a nucleus.
B. Both contain ribosomes.
C. Both contain membrane-bound organelles.
D. Both contain cell walls.
3. Both euglena (a protist) and cyanobacteria are photosynthetic unicellular organisms found in
pond water.
