    Question

    Bacterial cells are more resistant to osmotic shock than

    eukaryotic cells due to the-
    A cell wall composed of cellulose. Correct Answer Incorrect Answer
    B presence of osmoregulatory porins. Correct Answer Incorrect Answer
    C cell wall shows selective permeability. Correct Answer Incorrect Answer
    D cell wall composed of peptidoglycan. Correct Answer Incorrect Answer

    Solution

    Bacterial cells have a cell wall made of peptidoglycan, which provides structural integrity and protection against changes in osmotic pressure. This complex mesh-like structure can withstand both internal and external osmotic pressure changes better than eukaryotic cells, which generally do not have such a robust outer wall.
