Prokaryotic Cell Structure · NCERT Biology

The plasma membrane of prokaryotes is:

  1. Maintaining cell shape and preventing osmotic lysis
  2. Carrying out protein synthesis
  3. Storing reserve food materials
  4. Providing resistance to antibiotics
Show answer and explanation

Correct answer: Maintaining cell shape and preventing osmotic lysis

The cell wall provides strong structural support to the bacterium. It maintains the cell's shape and prevents it from collapsing or bursting (lysis) in a hypotonic medium.
