A bud is condensed, immature or embryonic shoot having a growing point surrounded by closely packed immature leaves. A bud which develops on the node but outside the leaf base is known as

Options

A. Axillary
B. Extra-axillary
C. Radical
D. Foliar

Answer

To solve the question regarding the type of bud that develops on the node but outside the leaf base, we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Definition of a Bud**:
- A bud is described as a condensed, immature, or embryonic shoot that has a growing point surrounded by closely packed immature leaves.

2. **Identifying the Key Terms in the Question**:
- The question specifies that the bud develops on the node but is located outside the leaf base.

3. **Analyzing the Options**:
- **Option 1: Agraric Bud**:
- Agraric buds are those that develop in the axil of a leaf, which is the angle between the leaf and the stem. Since the question states that the bud is outside the leaf base, this option does not fit.

- **Option 2: Extra Agraric Bud**:
- Extra agraric buds are those that grow on the stem but outside the leaf base. This aligns with the description provided in the question, making this a potential correct answer.

- **Option 3: Radical Bud**:
- Radical buds are responsible for the vertical growth of the plant and typically arise from the root area, not from the node. This option does not match the criteria.

- **Option 4: Foiler Bud**:
- Foiler buds grow on leaves other than the node, such as at the leaf base. This does not fit the requirement of being on the node.

4. **Conclusion**:
- Based on the analysis of the options, the correct answer to the question is **Extra Agraric Bud**, as it is the only type of bud that develops on the stem but outside the leaf base.

### Final Answer:
The bud which develops on the node but outside the leaf base is known as an **Extra Agraric Bud**.
