Which is incorrect about compound leaf?

Options

A. Lamina is completely broken into distinct leaflets
B. Incision of lamina reaches upto the midrib
C. Midrib forms a common axis called rachis
D. It contains bud at the axil of leaflets

Answer

To determine which statement is incorrect about compound leaves, we need to analyze the characteristics of compound leaves and compare them with the statements provided.

### Step-by-Step Solution:

1. **Understanding Compound Leaves**:
- A compound leaf is characterized by its structure, where the lamina (the leaf blade) is divided into multiple leaflets. Each leaflet can function independently, but they all attach to a common stem called the rachis.

2. **Identifying Features of Compound Leaves**:
- **Feature 1**: The lamina is divided into distinct leaflets. This is a defining characteristic of compound leaves.
- **Feature 2**: The incisions of the lamina can reach up to the midrib, which is the central vein of the leaf. This allows for deeper divisions in the leaf structure.
- **Feature 3**: The midrib forms a common axis known as the rachis, from which the leaflets arise.

3. **Analyzing the Statements**:
- **Statement 1**: "Lamina is completely broken into distinct leaflets." - This is correct for compound leaves.
- **Statement 2**: "Incision of lamina reaches up to the midrib." - This is also correct.
- **Statement 3**: "Midrib forms a common axis called rachis." - This is correct as well.
- **Statement 4**: "It contains bud at the axle of leaflet." - This is incorrect. Buds are typically found at the axil of simple leaves, not compound leaves.

4. **Conclusion**:
- The incorrect statement about compound leaves is that they contain buds at the axil of leaflets. This feature is characteristic of simple leaves.

### Final Answer:
The incorrect statement about compound leaves is: "It contains bud at the axle of leaflet."
