Find out the incorrect one (w.r.t. pinnate compound leaf)

Options

A. Feather like outline
B. Leaflets are attached to the tip of petiole (
C. Leaflets bearing axis is a continuation of petiole
D. Leaflets occur in two rows

Answer

To solve the question regarding the incorrect statement about pinnate compound leaves, we will analyze each option step by step.

### Step 1: Understanding Pinnate Compound Leaves
Pinnate compound leaves are characterized by their arrangement of leaflets along a central axis known as the rachis. This arrangement resembles the structure of a feather.

**Hint:** Recall the structure of a feather to visualize the arrangement of leaflets.

### Step 2: Analyzing the Options
1. **First Option: "It has a feather-like outline."**
- This statement is correct. Pinnate compound leaves indeed have a feather-like appearance due to the arrangement of leaflets along the rachis.

**Hint:** Think about how a feather is structured to confirm this option.

2. **Second Option: "The leaflets are attached to the tip of the petiole."**
- This statement is incorrect. In pinnate compound leaves, the leaflets are attached along the rachis, not at the tip of the petiole.

**Hint:** Visualize the connection points of leaflets to determine the accuracy of this statement.

3. **Third Option: "The leaflets are arranged in two rows."**
- This statement is correct. The leaflets in a pinnate compound leaf are typically arranged in two rows on either side of the rachis.

**Hint:** Consider how the leaflets are positioned relative to the rachis.

4. **Fourth Option: "The leaflets bear on the axis."**
- This statement is also correct. The leaflets are borne on the rachis, which is a continuation of the petiole.

**Hint:** Remember the terminology of leaf anatomy to validate this statement.

### Step 3: Conclusion
After analyzing all the options, we find that the second option, "The leaflets are attached to the tip of the petiole," is the incorrect statement regarding pinnate compound leaves.

**Final Answer:** The incorrect option is the second one.
