Find the odd pair

Options

A. Stomata : Transplration
B. Xylem : Transportation of food
C. Root hairs : Absorption of water
D. Chlorophyil : Photosynthesis

Answer

To find the odd pair from the given options, we need to analyze each term and its function in relation to plants.

### Step-by-Step Solution:

1. **Identify the Terms**: The terms we need to analyze are stomata, xylem, root hair, and chlorophyll.

2. **Understand the Functions**:
- **Stomata**: These are tiny pores on the surface of leaves that facilitate transpiration, which is the loss of water vapor from the plant.
- **Xylem**: This is a type of vascular tissue responsible for the transport of water and minerals from the roots to other parts of the plant.
- **Root Hair**: These are extensions of root cells that increase the surface area for absorption of water and nutrients from the soil.
- **Chlorophyll**: This is a pigment found in plants that is essential for photosynthesis, allowing plants to convert sunlight into energy.

3. **Compare the Functions**:
- Stomata and root hairs are involved in the process of water movement (transpiration and absorption).
- Xylem is involved in the transportation of water and minerals, while chlorophyll is involved in photosynthesis.

4. **Identify the Odd Pair**:
- Stomata, root hair, and chlorophyll are all directly related to processes that involve water and energy production in plants.
- Xylem, while important, is specifically a tissue type that does not directly participate in the processes like transpiration or photosynthesis. It mainly functions in the conduction of water and minerals.

5. **Conclusion**: The odd pair is **xylem** because it serves a different function compared to the other terms, which are more directly involved in the processes of water movement and energy production.

### Final Answer:
The odd pair is **B. Xylem**.
