The correct Answer is:
To answer the question "Heterogamous head is with," we need to understand the concept of heterogamous and homogamous heads in flowering plants, particularly in the context of inflorescence. ### Step-by-Step Solution: 1. **Understanding Heterogamous Head**: - A heterogamous head is characterized by the presence of two different types of florets in the inflorescence. - This means that it consists of more than one kind of flower structure. 2. **Identifying the Types of Florets**: - The two types of florets involved in a heterogamous head are: - **Ray Florets**: These are typically found at the edge of the flower head and are often sterile (neuter). - **Disc Florets**: These are located at the center of the flower head and are usually bisexual, meaning they contain both male and female reproductive organs. 3. **Distinguishing from Homogamous Head**: - In contrast, a homogamous head consists of only one type of floret, either all ray florets or all disc florets. This means it does not mix different types of florets. 4. **Conclusion**: - Therefore, a heterogamous head is formed by the combination of **ray florets and disc florets**. ### Final Answer: A heterogamous head is with **ray florets and disc florets**. ---
