Options

A. A-(iv),B-(iii),C-(ii),D-(i)
B. A-(iii),B-(iv),C-(ii),D-(i)
C. A-(ii),B-(iii),C-(iv),D-(i)
D. A-(iv),B-(ii),C-(iii),D-(i)

Answer

To solve the matching question between Column I and Column II, we need to analyze the characteristics of each xylem component listed in Column I and match them with the appropriate descriptions in Column II.

### Step-by-Step Solution:

1. **Identify the components in Column I:**
- A. Vessels
- B. Tracheids
- C. Xylem fibres
- D. Xylem parenchyma

2. **Analyze each component and its characteristics:**
- **A. Vessels:** These are specialized structures in xylem that are responsible for the conduction of water. They have thick walls and an obliterated central lumen (the central space is not functional for living cells).
- **B. Tracheids:** These are elongated cells in the xylem that also help in water conduction. They have perforations in their side walls that allow for water movement between cells.
- **C. Xylem fibres:** These are supportive cells that have thick, lignified walls and tapering ends. They provide structural support to the plant.
- **D. Xylem parenchyma:** This is the only living cell type in the xylem. It has thin cell walls made of cellulose and contains protoplasm.

3. **Match each component with the correct description:**
- **A. Vessels** match with **(ii)**: "Cells possess highly thickened walls with obliterated central lumen."
- **B. Tracheids** match with **(iii)**: "Individual members are interconnected through perforations in their common walls."
- **C. Xylem fibres** match with **(iv)**: "Elongated tube-like cells with thick, lignified walls and tapering ends."
- **D. Xylem parenchyma** match with **(i)**: "Cells are living, with thin cellulosic cell walls."

4. **Final Matching:**
- A → (ii)
- B → (iii)
- C → (iv)
- D → (i)

5. **Select the correct option based on the matches:**
- The correct option is: A-2, B-3, C-4, D-1.
