Across
- 2. part of the outer envelope of a bacterial cell
- 4. some prokaryotes tend to form this
- 5. prokaryotes that form aggregate communities are encased in a stabilizing matrix of this.
- 8. a general behavioral tendency of various archaea
- 11. provides structural support, protection, and is also a filtering mechanism
- 13. free sphere-shaped structures within the cytoplasm composed of RNA and protein
- 14. contains genetic material and so controls the activity of a prokaryotic cell; corresponds to a "nucleus"
Down
- 1. prokaryotic organisms that may be intermediates between bacteria and eukaryotes
- 3. a layer of lipids and proteins that forms the external boundary of the cytoplasm
- 6. a substance that composes the volume of a cell
- 7. an outgrowth that is used for motility and locomotion
- 9. a small extrachromosomal DNA molecule capable of replication
- 10. a bacterial organelle that invaginates the plasma membrane
- 12. external vertical filamentous projections
