Ligulate/strap-shaped corolla occurs in Sunflower in

Options

A. Disc florets
B. Immature florets
C. Ray florets
D. Both ray and disc florets.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Sunflower**: Sunflowers have a unique inflorescence known as a capitulum, which is a type of racemose head. This structure consists of a flattened peduncle that forms a receptacle.

2. **Identifying the Florets**: On the receptacle of the sunflower, there are numerous small flowers known as florets. These florets are sessile, meaning they do not have individual stalks (pedicels).

3. **Types of Florets**: The florets in a sunflower are arranged in two distinct rows:
- **Ray Florets**: These are located on the outer side of the receptacle. They are characterized by their ligulate or strap-shaped corolla and are typically sterile or female.
- **Disc Florets**: Found in the center of the receptacle, these florets are bisexual and tubular in shape.

4. **Identifying the Ligulate/Strap-shaped Corolla**: The question specifically asks about the ligulate or strap-shaped corolla found in sunflowers. This type of corolla occurs in the ray florets, which are the outer florets.

5. **Conclusion**: Therefore, the ligulate/strap-shaped corolla occurs in the ray florets of the sunflower.

**Final Answer**: The ligulate/strap-shaped corolla occurs in the ray florets of the sunflower.
