Which of the following is not a correct match?

Options

A. Petiole : attaches leaf to stem
B. Lamina : green flat part of leaf
C. Margin : gives shape to the leaf
D. Veins : transpiration

Explanation

To determine which of the following options is not a correct match, we need to analyze each option provided. Let's break it down step by step.

### Step 1: Analyze the First Option - Petiole
- **Definition**: The petiole is the stalk that attaches the leaf to the stem.
- **Correctness**: This is a correct match as the petiole's main function is indeed to connect the leaf to the stem.

### Step 2: Analyze the Second Option - Lamina
- **Definition**: The lamina is the broad, flat part of the leaf where photosynthesis occurs.
- **Correctness**: This is also a correct match since the lamina is essential for photosynthesis.

### Step 3: Analyze the Third Option - Margin
- **Definition**: The margin refers to the edge or outline of the leaf, which can vary in shape.
- **Correctness**: This is a correct match as the margin contributes to the overall shape and structure of the leaf.

### Step 4: Analyze the Fourth Option - Veins
- **Definition**: The veins in the leaf are responsible for transporting water and nutrients.
- **Correctness**: The statement that veins are known for transpiration is incorrect. Transpiration is the process of water loss through evaporation, primarily occurring through the lamina, not the veins.

### Conclusion
- The only incorrect match is the fourth option regarding veins. Therefore, the answer to the question "Which of the following is not a correct match?" is the option that states veins are known for transpiration.

### Final Answer
The option that is not a correct match is **Veins - Transpiration**.
