QUESTIONS:
1. For each of the organelles, describe its structure, give a major function, indicate whether it is
surrounded by a single membrane, a double membrane or no membrane, and state whether it is found
in a plant, animal, and/or bacterial cell.
2. Explain the importance of membranes and compartmentalization to cells.
3. Why are cells limited to a size smaller than 10 µm?
4. Describe the similarities in structure of mitochondria and chloroplasts. How are these similarities
related to the function of these organelles?
5. Distinguish between prokaryotic and eukaryotic cells.
6. Describe the basic structure of cilia and flagella in eukaryotes.
7.
Describe the structure of intercellular junctions found in plant and animal cells.
