1. Bacteria with a thin peptidoglycan layer and an outer membrane containing lipopolysaccharide (LPS).
3. A dormant, highly resistant structure formed by some bacteria to survive extreme environmental conditions.
5. Directed movement of bacteria toward favorable chemicals or away from harmful ones.
6. The region of the cytoplasm where the bacterial chromosome is concentrated.
8. Wall A rigid structure outside the plasma membrane that maintains cell shape and prevents bursting.
10. A toxic component of the Gram-negative outer membrane that acts as an endotoxin.
11. An organism, often an archaeon, that thrives in extreme environments such as high heat, salt, or acidity.
13. A small, circular piece of extrachromosomal DNA that often carries genes for antibiotic resistance or toxins.
14. A polysaccharide coating outside the cell wall that aids in protection and attachment.

1. Bacteria with a thick peptidoglycan layer in their cell wall that stain purple during Gram staining.
2. Small cellular structures responsible for protein synthesis in prokaryotic cells.
4. Long, whip-like structures used by bacteria for movement.
7. A dense, well-organized glycocalyx that enhances pathogenicity and protects bacteria from host defenses.
9. Short, bristle-like structures that allow bacteria to adhere tightly to host cells.
12. A community of bacteria embedded in a protective matrix that allows them to adhere to surfaces and resist removal.
13. Hair-like structures involved in conjugation and the transfer of genetic material between bacteria.
