Which of the following is a protective structure in bacterial cells?
Correct answer: A. Cell wall
- A. Cell wall
- B. Protoplasm
- C. Cellulose
- D. Nuclei
Explanation
In bacteria, the cell wall is made of peptidoglycan, which is a very strong in complex compound that helps in maintaining its structure and turgidity. Nuclei and protoplasm play no protective function. Cellulose is present in plants as their cell wall is made of it.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
