Exam points

  • identify a cell wall outside the plasma membrane in prokaryotic or plant cells
  • link cell-wall support to reduced swelling or bursting in dilute solutions

AP Biology 2.4 B Describe the Role of the Cell Wall in Maintaining Cell Structure and Function Questions question 1

[Maximum number: 1]

Intact cells of two unknown cell types were placed into solutions with different concentrations of NaCl. Type I
cells swelled and burst in the solution with the lowest concentration of NaCl. Type II cells swelled but did not
burst in the solution with the lowest concentration of NaCl.
Which of the following descriptions of cell type I and cell type II are most consistent with the data?

A

Cell Type I: Animal cell surrounded by a plasma membrane only; Cell Type II: Plant cell surrounded by a plasma membrane and a cell wall

B

Cell Type I: Plant cell surrounded by a plasma membrane only; Cell Type II: Bacterial cell surrounded by a cell wall only

C

Cell Type I: Plant cell surrounded by a plasma membrane only; Cell Type II: Animal cell surrounded by a plasma membrane and a cell wall

D

Cell Type I: Animal cell surrounded by a cell wall only; Cell Type II: Bacterial cell surrounded by a plasma membrane only
