Answered
(a) A virus without a capsid is called a naked virus. These viruses lack the protein coat (capsid) that typically surrounds and protects the viral genome. Without a capsid, these viruses are more susceptible to environmental degradation. (b) The structure of bacteria typically includes: 1. Cell membrane: A lipid bilayer that regulates material entry and exit. 2. Cytoplasm: Contains the cell’s genetic material and machinery. 3. Ribosomes: Sites of protein synthesis. 4. Nucleoid: Contains the bacterial chromosome, which is a single, circular DNA molecule. 5. Cell wall: Made of peptidoglycan in most bacteria, providing structural support. 6. Flagella: For movement in some bacteria. 7. Pili/fimbriae: For attachment to surfaces.
