Question

Which region of the root is responsible for the increase in root length?

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant anatomy and root growth
	**Related Topics**: Meristematic tissue, cell elongation, root zones
	**Prerequisites**: Basic understanding of plant cell structure and function.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the root region responsible for increased root length.
	Options: Root cap, root hair zone, zone of elongation, zone of maturation.
**Method & Steps**:
	1. **Understanding Root Zones**:  Roots are composed of distinct zones: the root cap, the zone of cell division (meristem), the zone of elongation, and the zone of maturation (differentiation).
		Reasoning: Each zone has a specific function in root growth and development.
		Formula/Rule: None directly applicable.
	2. **Identifying the Elongation Zone**: The zone of elongation is where newly formed cells from the meristem significantly increase in length. This elongation is the primary driver of root length increase.
		Working: The root cap protects the meristem, the root hair zone absorbs water and nutrients, and the zone of maturation is where cells differentiate into specialized tissues.  Only the zone of elongation directly contributes to length increase.
		Key Point: Cell division occurs in the meristem, but significant lengthening happens in the elongation zone.
	3. **Conclusion**: The zone of elongation is responsible for the increase in root length.
		Result: Zone of elongation (Option C)
		Verification:  Understanding the function of each root zone confirms this answer.
## OPTION ANALYSIS
A :x: Root cap: Protects the apical meristem but doesn't elongate significantly.
B :x: Root hair zone: Involved in water and nutrient absorption, not length increase.
C ✓: Zone of elongation: Cells in this zone undergo significant elongation, directly causing root length increase.
D :x: Zone of maturation: Cells differentiate into specialized tissues, but elongation is minimal.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the zone of elongation with the zone of cell division: While cell division provides the cells for elongation, it's the elongation itself that increases length.
			How to avoid: Remember that elongation is a distinct process from cell division.
		2. Selecting the root hair zone: Root hairs increase surface area for absorption, not root length.
			How to avoid: Focus on the process of lengthening, not nutrient uptake.
	**Quick Tips**:
		1. Visualize the root zones and their functions.
		2. Remember the order of root zones: root cap, meristem, elongation, maturation.
