Find out the maismatch pair

Options

A. Tracheids- Elongated or tube like cells with thick and lignified walls .These are dead and without protoplast.
B. Vessels-Tube like structure made up of many cells called vessel members , each wisth lignified walls and large central caivty. These are devoid of protoplasm
C. Xylem fibres-Highly thickened walls and obliterated central lumen
D. Xylem parenchyma- Living and thin walled cellulosic cells .They store food materials in the form of resin latex and mucilage

Explanation

To find the mismatch pair from the given options regarding the components of xylem and their functions, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of Xylem**:
- The main components of xylem include tracheids, vessels, xylem fibers, and xylem parenchyma.

2. **Analyze Each Pair**:
- **Tracheids**:
- Description: Elongated tubular cells with thick and lignified cell walls.
- Function: Conduction of water.
- Status: Dead without protoplast.
- **Conclusion**: This statement is correct.

- **Vessels**:
- Description: Tubelike structures made up of many cells called vessel members, each with lignified walls and a large central cavity.
- Function: Conduction of water.
- Status: Dead without protoplast.
- **Conclusion**: This statement is correct.

- **Xylem Fibers**:
- Description: Highly thickened walls and obliterated central lumen.
- Type: Sclerenchymatous cells.
- **Conclusion**: This statement is correct.

- **Xylem Parenchyma**:
- Description: Living cells with thin cell walls.
- Function: Storing food materials.
- Incorrect Statement: They store food in the form of raisins, latex, and mucilage.
- **Correct Information**: They actually store food in the form of starch and fat.
- **Conclusion**: This statement is incorrect.

3. **Identify the Mismatch Pair**:
- From the analysis, the mismatch pair is the description and function of xylem parenchyma, as it incorrectly states the form of stored food materials.

4. **Final Answer**:
- The incorrect match is related to xylem parenchyma, which states they store food materials in the form of raisins, latex, and mucilage instead of starch and fat.
