E) O two of the above.
What is the importance of nutrient uptake for a cell? What are the common features of nutrient uptake by bacteria?
Bacteria use many different modes of nutrition. Please discuss these modes using the terms photoautotroph, photoheterotroph, chemoautotroph and chemoheterotroph.
