Question

Assertion : Auxins promote apical dominance by suppressing the activity pf lateral buds.
Reason : In moriculture, periodic pruning of shoot tips is done to make mulberry plants bushy.

• A. If both the assertion and reason are true and the reason is a correct explanation of the assertion
• B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
• C. If the assertion is true but the reaon is false
• D. If both the assertion and reason are false
• E. If the assertion is false but reason is true

Answer 1

The correct option is A If both the assertion and reason are true and the reason is a correct explanation of the assertion

Auxin is produced by shoot tip and acts as a growth promoter for apical bud and inhibit the growth of lateral buds. When a terminal bud is removed, the nearest axillary buds begin to grow and the plant branches rapidly. In case of mulberry plants, pruning is done to remove apical dominance and causes more branching of the main body of the plant.
