Viruses cannot be grown on artificial culture media because they are:
Correct answer: C. Obligate intracellular parasites
- A. Facultative parasites
- B. Endoparasites
- C. Obligate intracellular parasites
- D. Ectoparasites
Explanation
Option C is correct. Viruses cannot be grown in anificial media because they lack metabolic machinery for the synthesis of their own nucleic acids and proteins. Facultative parasites are organisms that can live as either parasites or free-living organisms. Endoparasites are organisms that live inside the cells of their hosts. Viruses are not able to live on their own. They need to infect a host cell in order to replicate. Obligate intracellular parasites are organisms that can only live and reproduce inside the cells of a host organism. They are unable to live or reproduce on their own. Ectoparasites are organisms that live on the outside of their hosts.

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.
