EXTERNAL STRUCTURES OF PROKARYOTES

EXTERNAL STRUCTURES OF PROKARYOTES

1. FLAGELLA

   • appendages that extend outward from cell wall
   • movement and swarming

2. CELL WALL

   • made of peptidoglycan
   • maintain the shape of the cell

3. GLYCOCALYX

   • produce inside(excreted to the cell surface)
   • protect cell from phagocytosis

4. CONJUGATION PILI

   • longer than fimbriae
   • 1 or 2 per cell
   • sem pili
   • transfer DNA

5. FIMBRIAE

   • evenly distructed
   • can number anywhere
   • occur at the poles

6. AXIAL FILAMENT

   • fibrils that arise at the outer sheath of cell
   • similar like flagella but it wraps around the cell
