Bacteria are a kingdom of prokaryotic organisms. Bacteria possess circular DNA that does not exist in a nucleus, and bacteria usually have very few complex organelles. Furthermore, bacteria tend to live in moderate environments as opposed to the extreme environments inhabited by archaea....
Auxinspromote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. ... This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining...
