Based on this information, select all the of the following statements that are true.A) Penicillin affects bacteria but not eukaryotic animal cells.B) Bacterial cells that had already formed their cell walls would be unaffected.C) Penicillin would stop the growth of active colonies of susceptible bacteria.D) Penicillin affects bacterial cell walls and eukaryotic plant cell walls.
What will be an ideal response?
A, B, C
Eukaryotic cells in general will not be affected by penicillin. Animal cells do not have a cell wall and plant cell walls are constructed differently from bacterial cell walls. It is also true that bacteria that have already formed their cell walls would be unaffected and that penicillin would stop the growth of active colonies of susceptible bacteria.
