Question

The type of plant growth which is primarily regulated by the balance between auxins and cytokinins(SET2025)

• A. Apical dominance
• B. Leaf senescence
• C. Lateral root formation
• D. Fruit development

Answer 1

Answer:

A. Apical dominance

Auxins promote apical dominance by inhibiting the growth of lateral buds, while cytokinins encourage lateral bud growth, so their relative concentration determines which buds develop more actively, leading to the characteristic "dominant" apical bud.
