Sugary envelope that surrounds the cells (loosely or tightly) to promote attachment and prevent immune detection CS 19. Proteinaceous, sticky bristleb that can be used for attachment & biofilms. 20. If this structure connects the cytoplasm of two bacteria, one of the cells may gain new genetic material. 21. Which is the bacterial structure that acts as a selective barrier, allowing nutrients to enter the cell and wastes to leave the cell? 22. Although not present in all bacteria, this cell covering often enables cells that possess it to resist the defenses of host organisms, especially their phagocytic cells. 23. Prokaryotes' essential genetic information is located in the 24. Which of the following is an important source of endotoxin in gram-negative species? 25.
