Agricultural engineering and Bioengineering: what is the difference?

What's the difference between bioengineering and biomolecular engineering?

• Answer:

  Biomolecular engineering focuses on the modification and creation of molecules as compared to bigger structures and is thus a subfield of bioengineering. The bulk of bioengineering deals on the molecular level anyway, so often there is not much distinction in the methods being used. The result of bioengineering should be somehow visible on the level of cells, tissues or entires organisms, while biomolecular engineering can focus on molecules exclusively and is therefore closer to chemical engineering.
