Read the following statements: i. Membrane-bounded inclusion bodies are not found in prokaryotic cells. ii. Ribosomes are the site of protein synthesis. iii. Pili are the surface structure of the bacteria which may play a role in motility. iv. The cell membrane of prokaryotes is structurally similar to the eukaryotes. Choose the option with the correct statements.
Options
- Ai, ii, iii and iv
- Bii, iii and iv
- Ci, ii and iv
- Di, iii and iv
Correct answer
C. i, ii and iv
Step-by-step solution
Pili are thin, hair-like appendages on the surface of bacteria. They are rigid in appearance than flagella, which have motility function. Bacteria use sex pili for the process of conjugation. Pili also function as receptors for donor-specific (male-specific) phages.
