Question

The growth of apical bud stops the growth of the axillary bud. This phenomena is known as

• A. Apical dominance
• B. Photomorphogenesis
• C. Photoperiodism
• D. None of the above

Answer 1

The correct option is A Apical dominance

When there is the presence of the apical bud in a plant, there is suppression of the growth of the lateral buds and this phenomenon is called as apical dominance. The hormone auxin produced at these tips causes the growth and elongation of only the apical bud by maintaining the concentration. The removal of the apical bud allows growth of the lateral bud.

Thus, the correct answer is option A.
