The four important structural and functional aspects of prokaryotes are
1) Morphology (shape)
2) Motility (movement)
4) Metabolic Diversity (Energy)
is the shape of the cell. Bacteria can be bacilli (bar), Cocci (spheres), or Spirilla (spiral).
What is the most important aspect of prokaryotic morphology?
the size of the cell
small cells allow for
rapid exchange of wastes and nutrients across cell membranes and have higher metabolic and growth rates.
the ability of an organism to move and it mechanism of movement.
prokaryotes move by (3)
1) gliding along solid surfaces
2) using gas vesicals to move in water
3) Flagella (most)
What are the three locations of flagella?
1) on the ends (POLAR)
2) all around (peritrichous)
3) tuft at one end (lophotrichous)
