  2. 7. .......... show a range in the number and arrangement of flagella.
  3. 8. Several ribosomes may attach to a single mRNA and form a chain called .......... or polysome.
  4. 9. Besides flagella, ......... and ......... are also surface structures of the bacteria but do not play a role in motility.
  5. 11. They are about 15 nm by 20 nm in size and are made of........ subunits - 50S and 30S units which when present together form 70S prokaryotic ribosomes.
  6. 13. The ribosomes of a polysome ............ the mRNA into proteins.
  7. 14. Reserve material in prokaryotic cells are stored in the cytoplasm in the form of ............bodies.
  8. 16. Bacterial cells may be .......... or non-motile.

  1. 1. The fimbriae are small ....... like fibres sprouting out of the cell.
  2. 2. If motile, they have thin filamentous extensions from their cell wall called ............
  3. 3. In prokaryotes, ribosomes are associated with the ........... of the cell.
  4. 5. vacuoles .............. are found in blue green and purple and green photosynthetic bacteria.
  5. 6. In some bacteria, they are known to help attach the bacteria to ......... in streams and also to the ....... tissues.

  7. 10. ......... are the site of protein synthesis.
  8. 12. Bacterial flagellum is composed of three parts – filament, hook and..........
  9. 15. These are ........... by any membrane system and lie free in the cytoplasm, e.g., phosphate granules, cyanophycean granules and glycogen granules.
