Question

Cytokinins are primarily involved in:

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant hormone functions
	**Related Topics**: Plant growth regulators, cell cycle, senescence, apical dominance, dormancy
	**Prerequisites**: Basic understanding of plant physiology and the roles of different plant hormones.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the primary role of cytokinins.
**Method & Steps**:
	1. Recall the functions of cytokinins.
		Reasoning: Cytokinins are a class of plant hormones that regulate various aspects of plant growth and development.
		Formula/Rule: N/A
	2. Identify the primary function of cytokinins among the given options.
		Working: Cytokinins are primarily known to stimulate cell division (cytokinesis), hence their name. While they are involved in other processes like apical dominance, they are not primarily associated with it.
		Key Point:  The other options are related to other plant hormones or are secondary effects of cytokinin action.
	3. Select the option that best describes the primary role of cytokinins.
		Result: Cell division (option C)
		Verification: The function aligns with the established knowledge of cytokinin's role in plant growth and development.
## OPTION ANALYSIS
A :x: Apical dominance is mainly regulated by auxins, although cytokinins play a counteracting role.
B :x: Senescence is associated with abscisic acid and ethylene.
C ✓: Cell division is the primary function of cytokinins.
D :x: Dormancy is primarily regulated by abscisic acid.
## LEARNING AIDS
	**Common Mistakes**:
		1.Confusing the roles of different plant hormones:  Understanding the specific functions of auxins, gibberellins, abscisic acid, ethylene, and cytokinins is crucial.
			How to avoid: Create a table summarizing the primary functions of each hormone.
		2.Focusing on secondary effects: Cytokinins are involved in multiple processes, but cell division is their primary function.
			How to avoid:  Learn to differentiate between primary and secondary effects of a hormone.
	**Quick Tips**:
		1.Remember the root word 'cyto' relating to cells and 'kinin' relating to movement/division.
		2.Associate cytokinins with cell division and shoot growth.
