Bacteria differ from viruses in:
Correct answer: B. Having well-defined cytoplasm
- A. Pathogenic nature
- B. Having well-defined cytoplasm
- C. Genetic material
- D. Lacking proper nucleus
Explanation
Bacteria are unicellular organisms that have well-defined cellular structures, including a well-defined cytoplasm. They have cell membranes, cytoplasm, ribosomes, and other cellular components that are essential for carrying out various life processes. In contrast, viruses are not cells and lack cellular structures like cytoplasm. Instead, viruses consist of genetic material (DNA or RNA) surrounded by a protein coat.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
