Select the correct statement with respect to plant organs

Options

A. A bud is present in the axil of petiole in both simple and compound leaf.
B. Swollen leaf base occurs in Solanaceae
C. Stem tendril occurs in pea
D. Phylloclade is expanded petiole which becomes green and photosynthetic

Answer

To solve the question regarding the correct statement with respect to plant organs, we will analyze each of the four statements provided.

### Step-by-Step Solution:

1. **Understanding the Statements**:
We need to evaluate four statements about plant organs to determine which one is correct.

2. **Analyzing Statement 1**:
- The statement claims that "a bud is present in the axil of the petiole in both simple and compound leaves."
- **Explanation**: In both simple and compound leaves, there is indeed an axillary bud located in the axil (the angle between the leaf and the stem). This statement is **true**.

3. **Analyzing Statement 2**:
- The statement claims that "the swollen leaf base occurs in Solanaceae."
- **Explanation**: The swollen leaf base, known as a pulvinus, is characteristic of the Leguminosae family (e.g., peas, beans), not Solanaceae (the nightshade family). This statement is **false**.

4. **Analyzing Statement 3**:
- The statement claims that "stem tendrils occur in pea."
- **Explanation**: In pea plants, tendrils are actually leaf modifications, not stem modifications. Therefore, this statement is also **false**.

5. **Analyzing Statement 4**:
- The statement claims that "the phylloclad is the expanded petiole which becomes green and photosynthetic."
- **Explanation**: Phylloclades are indeed green stems that have adapted to perform photosynthesis, but they are not expanded petioles. This statement is **false**.

6. **Conclusion**:
After evaluating all four statements, we find that only the first statement is correct. Therefore, the correct answer to the question is **Statement 1**.

### Final Answer:
The correct statement with respect to plant organs is: **A bud is present in the axil of the petiole in both simple and compound leaves.**
