Indeterminate Growth & Open Development — NEET Biology
📚 Practice Concept'Both growth and differentiation in higher plants are open'. Comment.
Assertion (A): Apical dominance occurs in all higher plants without exception. Reason (R): The growing apical bud contains auxins that inhibit lateral bud growth.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT states “In most higher plants, the growing apical bud inhibits the growth of the lateral (axillary) buds, a phenomenon called apical dominance.” The Assertion removes “most” making it false - some higher plants may not show apical dominance. The Reason is true from NCERT, explaining the mechanism of apical dominance through auxin action.
