How does auxin promote the growth of a tindril around a plant. Name the growth inhebetr in plant
Answers
Auxin is plant hormone which is synthesized at the tip of the shoot. It helps the cell grow longer. When a tendril comes in contact with a support, auxin stimulates faster growth of the cells on the opposite side that's why the tendril forms a coil around the support.
These chemicals inhibit growth and promote dormancy and abscission in plants. An example is an abscisic acid.
Ethylene can be a promoter or an inhibitor, but is largely a Plant Growth Inhibitor.
Hope it helps...
When the tip of a tendril touches a support , then the auxins present in its tip move to that side of tip which is away from the support . Auxins promote growth . So due to more auxins in it , the side of tendril away from the support grows faster than the side which is in contact with the support and makes the tendril twirl around the support .
Abscisic acid is the growth inhibitor in plants .
