1. Question 1
   A nurse is reviewing why some bacteria are harder for the immune system to clear. Which cell-boundary structure is most directly associated with helping certain bacteria evade phagocytosis and adhere to surfaces?

   Cell wallCapsule (glycocalyx)Extracellular matrixPlasma membrane

   Check Answer
2. Question 2
   A nursing student is comparing boundary structures of different cell types. Which structure is selectively permeable and regulates what enters and leaves all living cells?

   Capsule (glycocalyx)Cell wallExtracellular matrix (ECM)Plasma membrane

   Check Answer
3. Question 3
   A lab technician observes a eukaryotic cell with a thick, rigid outer layer that maintains cell shape and helps prevent osmotic swelling. Which cell-boundary structure best explains this finding?

   Cell wallPlasma membraneExtracellular matrix (ECM)Capsule (glycocalyx)

   Check Answer
4. Question 4
   A patient is prescribed an antibiotic that inhibits peptidoglycan cross-linking. Which cell-boundary structure is most directly weakened by this medication?

   Check Answer
5. Question 5
   A nurse is teaching students why some organs (like the skin and intestinal lining) have strong, stable tissue structure. Which cell-boundary-related structure in animal cells primarily provides external support and helps anchor cells to each other through proteins like collagen?
