In a raceme, the flower arrangement is

Options

A. basipetal
B. centripetal
C. centrifugal
D. acropetal

Answer

**Step-by-Step Solution:**

1. **Understanding Raceme**: A raceme is a type of inflorescence where flowers are arranged along a central stem or axis. It is important to know that the arrangement of flowers in a raceme follows a specific pattern.

2. **Identifying Flower Arrangement Types**: The options provided for the arrangement of flowers in a raceme are:
- Basipetal
- Centripetal
- Centrifugal
- Acropetal

3. **Excluding Incorrect Options**:
- Centripetal and centrifugal arrangements can be excluded because they do not apply to the arrangement of flowers in a raceme.
- This leaves us with basipetal and acropetal as the two possible options.

4. **Understanding Acropetal Arrangement**: In a raceme, flowers are arranged in an acropetal succession. This means that the younger flowers are located at the top (apex) of the raceme, while the older flowers are found at the bottom (base).

5. **Understanding Basipetal Arrangement**: Basipetal arrangement, on the other hand, is characterized by older flowers being at the top and younger flowers at the bottom. This type of arrangement is typically found in a different type of inflorescence called thyrse.

6. **Conclusion**: Based on the characteristics of a raceme, the correct answer is that the flower arrangement in a raceme is acropetal, where younger flowers are at the apex and older flowers are at the base.

**Final Answer**: In a raceme, the flower arrangement is acropetal.
