Question

Rhizosphere is closely related to

• A. Soil structure
• B. Soil texture
• C. Plant root system
• D. Wilting range

Hint:

Rhizosphere:
- Region around plant roots.
- Influenced by root exudates.
- High microbial activity.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question tests knowledge of the rhizosphere and its relationship to plant roots.

Step 2: Detailed Explanation:
The rhizosphere (C) is closely related to the plant root system.
It is the narrow region of soil directly influenced by root secretions and associated microorganisms.
The rhizosphere is the zone of high microbial activity around plant roots.
Other options:
- Soil structure (A): The arrangement of soil particles.
- Soil texture (B): The proportion of sand, silt, and clay.
- Wilting range (D): The soil moisture content at which plants wilt.
Thus, the rhizosphere is related to the plant root system.

Step 3: Final Answer:
Thus, the rhizosphere is closely related to the plant root system, which corresponds to option (C).
