Across
- 4. Cascade of serum proteins that, when activated, leads to the lysis and removal of pathogens
- 5. Whip-like appendages found on some bacteria that enable movement
- 8. Immune cells that engulf and digest foreign substances and pathogens
- 9. Small signaling molecules secreted by immune cells to regulate inflammation and cellular responses
Down
- 1. Cellular “factories” where protein synthesis occurs in both prokaryotes and eukaryotes
- 2. Biological preparation used to stimulate the adaptive immune system and provide protection against diseases
- 3. Gelatinous layer, often made of polysaccharides, that surrounds and protects some bacteria
- 6. Y-shaped proteins produced by B-cells that help neutralize pathogens
- 7. Region in a prokaryotic cell where the genetic material is localized (not enclosed by a nuclear membrane)
