Maximum growth of root occurs

Options

A. At the tip
B. Behind the tip
C. Root hair zone
D. In light

Answer

To solve the question "Maximum growth of root occurs," we can follow these steps:

### Step 1: Understand the Structure of Roots
Roots consist of different zones, each with specific functions. The main zones include:
- Root cap
- Meristematic zone
- Elongation zone
- Maturation zone (or root hair zone)

### Step 2: Identify the Growth Zones
Among these zones, the meristematic zone is crucial for growth. This zone contains meristematic tissues that are actively dividing and responsible for the growth of the root.

### Step 3: Locate the Meristematic Zone
The meristematic zone is located just behind the root tip. This is where the cells are actively dividing, leading to the elongation of the root.

### Step 4: Analyze the Options
- **Option A (At the tip)**: The root tip is protected by the root cap and does not have active growth.
- **Option B (Behind the tip)**: This is where the meristematic tissue is located, indicating maximum growth.
- **Option C (Root hair zone)**: This zone is involved in absorption, not growth.
- **Option D (In light)**: Roots typically grow in the absence of light, as they are underground.

### Step 5: Conclusion
Based on the analysis, the maximum growth of a root occurs **behind the tip**, where the meristematic tissue is located.

### Final Answer
The correct answer is **Option B: Behind the tip**.
