Auxin is a plant hormone that controls the growth of the plant neear the tips, shoots and roots.
It controls the response to light (Photoropism), gravity (gravitropism) and moisture.
Auxin is produced in the tips and moves bach to stimulate cell elongation.
If the tip is removed then no auxin is produced and the plant stops growing.
Extra auxxin promotes the growth in the shoot bu inhibits growth in the root.
