RACEMOSE

Options

A. Datura
B. Saraca
C. Casuarina
D. Cotton

Answer

To determine which of the given options represents a racemose inflorescence, we need to understand the characteristics of racemose and cymose inflorescences.

### Step-by-Step Solution:

1. **Understand Inflorescence Types**:
- Inflorescence refers to the arrangement of flowers on a plant. There are two main types: racemose and cymose.

2. **Define Racemose Inflorescence**:
- In racemose inflorescence, the main axis continues to grow indefinitely, and flowers are borne laterally along this axis. The arrangement is acropetal, meaning that the younger flowers are at the top and older flowers are at the bottom.

3. **Define Cymose Inflorescence**:
- In cymose inflorescence, the growth is determinate, meaning the main axis stops growing once the terminal flower blooms. Flowers are borne at the top, leading to a basipetal arrangement (younger flowers are at the bottom).

4. **Analyze the Given Options**:
- The options provided are:
- A) Datura
- B) Casuarina
- C) Cassia
- D) Cotton

5. **Identify the Correct Option**:
- Among the options, Casuarina is known to exhibit racemose inflorescence. The other options (Datura, Cassia, and Cotton) are examples of cymose inflorescence.

6. **Conclusion**:
- Therefore, the correct answer is **B) Casuarina**, as it represents a racemose inflorescence.
