The type of leaf in Daucus carota is

Options

A. simple
B. bipinnate
C. tripinnate
D. decompound

Answer

To determine the type of leaf in Daucus carota, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Plant**:
- Daucus carota is commonly known as wild carrot and belongs to the Apiaceae family.

2. **Understand Leaf Types**:
- Leaves can be classified into two main categories: simple and compound.
- **Simple Leaf**: A single leaf blade that is not divided into smaller leaflets.
- **Compound Leaf**: A leaf that is divided into multiple leaflets attached to a single midrib.

3. **Differentiate Compound Leaf Types**:
- Compound leaves can further be categorized based on their pination:
- **Pinate**: Leaflets are arranged along a central axis (rachis).
- **Bipinate**: Leaflets are arranged in a pinate manner on the rachis, meaning each leaflet is further divided into smaller leaflets.
- **Tripinate**: Leaflets are arranged in a bipinate manner, where each bipinate leaflet is again divided into smaller leaflets.
- **Decompound**: A more complex structure where leaflets are arranged multiple times, resulting in a highly divided leaf structure.

4. **Analyze Daucus carota Leaf Structure**:
- Upon examining Daucus carota, we find that its leaves are highly divided and consist of multiple leaflets arranged in a complex manner.

5. **Conclude the Leaf Type**:
- Based on the structure of the leaves in Daucus carota, we can conclude that they are classified as **decompound leaves**.

6. **Select the Correct Option**:
- Therefore, the correct answer to the question is **option 4: decompound leaf**.
