Question

Study the following statements and select the correct ones.

• A. Auxin is transported from base to tip in large quantities.
• B. Cells on the dark side expand farther than those on the light side.
• C. Apical dominance can be removed the decapitation
• D. Tropic movements in plants are under the control of gibberellins

Answer 1

The correct option is C Apical dominance can be removed the decapitation

Decapitation involves cutting of apical bud in plants. When the apical bud is removed, the source of auxin is removed. Auxin causes apical dominance. Since the auxin concentration is much lower, the lateral buds can now grow. In fact, their growth will be stimulated by a relatively small drop in auxin concentration. Thus, decapitating a shoot will cause it to branch.

So, the correct option is 'Apical dominance can be removed the decapitation'.
