Question

The plant hormone which counteracts apical dominance is

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Hormones and their Functions
	**Related Topics**: Apical Dominance, Auxin, Cytokinin, Ethylene, Abscisic Acid (ABA)
	**Prerequisites**: Basic knowledge of plant hormones and their roles in plant growth and development.
## SOLUTION PATHWAY
**Given Information**:
	The question asks for the plant hormone that counteracts apical dominance.
**Method & Steps**:
	1.  Recall the function of each listed plant hormone regarding apical dominance.
		Reasoning: Apical dominance is primarily promoted by auxin. The hormone that counteracts this should inhibit apical growth and promote lateral growth.
		Formula/Rule: None
	2.  Identify the hormone that promotes lateral bud growth, thereby counteracting apical dominance.
		Working: Cytokinin is known to promote lateral bud growth and inhibit apical dominance.
		Key Point: Auxin promotes apical dominance, while cytokinins counteract it.
	3.  Select the correct answer.
		Result: Cytokinin is the hormone that counteracts apical dominance.
		Verification: This is a well-established concept in plant physiology.
 ## OPTION ANALYSIS
[A] :x: Auxin promotes apical dominance, it does not counteract it.
[B] ✓: Cytokinin is the correct hormone that counteracts apical dominance.
[C] :x: Ethylene is involved in fruit ripening, senescence, and stress response, not directly in counteracting apical dominance.
[D] :x: ABA (Abscisic acid) is involved in stress response and dormancy, not in counteracting apical dominance.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the roles of auxin and cytokinin: Remember that auxin promotes apical dominance, while cytokinin promotes lateral bud growth.
		2. Overlooking the specific function of the hormone in relation to the question: Focus on the direct role of each hormone in apical dominance.
	**Quick Tips**:
		1. Visualize the plant: Think about how auxin promotes vertical growth and cytokinin promotes branching.
		2. Use mnemonic: 'C' for Cytokinin and 'Counteract' to remember its role in counteracting apical dominance.
