Which Hormone Plays an "Anti-Abscission Role" in Plants

Question

Which hormone plays an "anti-abscission role" in plants?
A) auxin
B) ethylene
C) gibberellin
D) cytokinin

Accepted Answer

Auxin plays an "anti-abscission role" in plants by inhibiting the formation of the abscission zone, a layer of cells that breaks down and allows for the separation of leaves, flowers, and fruits from the plant. This helps in retaining leaves, flowers, and fruits on the plant for a longer period of time.
