Question

Which part of the root is responsible for the absorption of water and minerals from the soil?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant Anatomy and Physiology
 **Related Topics**: Root structure, water uptake, mineral absorption, xylem
 **Prerequisites**: Basic understanding of plant cells and tissues.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the part of the root responsible for absorbing water and minerals.
  Options include root cap, root hairs, meristematic zone, and zone of elongation.
**Method & Steps**:
 1. Identify the function of each part of the root.
  Reasoning: Each part of the root has a specific role in its growth and function.
 2. Determine which part is specialized for absorption.
  Working: Root hairs are tiny, hair-like extensions of the epidermal cells in the root. Their large surface area significantly increases the area available for water and mineral absorption from the soil.
  Key Point: The root cap protects the apical meristem, the meristematic zone is responsible for cell division, and the zone of elongation is responsible for cell elongation, none of which are directly involved in absorption.
 3. Select the correct option.
  Result: Root hairs are responsible for the absorption of water and minerals from the soil.
  Verification: This aligns with established knowledge of plant anatomy and physiology.
 ## OPTION ANALYSIS
A :x: Root cap: Protects the apical meristem (growing tip) of the root.
B ✓: Root hairs:  Their large surface area maximizes water and mineral absorption.
C :x: Meristematic zone: Region of cell division and growth, not primarily involved in absorption.
D :x: Zone of elongation: Region where cells lengthen, not primarily involved in absorption.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing root hairs with other root structures:  Understanding the specific function of each root part is key.
  2. Focusing on overall root function instead of specific absorption: The question asks for the *part* responsible for absorption, not the root's general function.
 **Quick Tips**:
  1.Remember the large surface area of root hairs is crucial for absorption.
  2.Visualize the root structure and assign functions to each part.
