Please help! How is the growth of the roots affected by the auxin concentration at which stems grow the most?

Explanation:

Auxins change the rates of elongation in plant cells and control growth of stems and roots. Stems and roots respond differently to high concentrations of auxins: cells in stems grow more. cells in roots grow less

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
