Consider statements about microorganisms: 1. Bacteria are prokaryotes. 2. Fungi are eukaryotes. 3. Viruses have a cellular structure. Which are correct?
A. 1 and 3 only
B. 1 and 2 only
C. 1, 2 and 3
D. 2 and 3 only
Answer: Option B
Solution (By JKSSB Mock Tests)
Bacteria are unicellular prokaryotic organisms, characterized by the absence of a true, membrane-bound nucleus and other membrane-bound organelles. Fungi are eukaryotic organisms, possessing a true nucleus and membrane-bound organelles, and can be unicellular (yeasts) or multicellular (molds, mushrooms). Viruses are acellular, non-cellular entities; they consist of genetic material (DNA or RNA) enclosed in a protein coat (capsid) and lack any cellular structure or independent metabolic machinery. Thus, statements 1 and 2 are correct.
