Select the correct statement for racemose inflorescence

Options

A. The shoot axis shows definite growth
B. Flowers are borne in basipetal succession
C. Flowers are borne in acropetal succession
D. Older flowers are present towards the apex and younger flowers are present at the base

Answer

To solve the question regarding the correct statement for racemose inflorescence, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding Racemose Inflorescence**:
- Racemose inflorescence is characterized by the indefinite growth of the main axis, which means that the terminal bud continues to grow. This allows for the formation of flowers along the axis.

**Hint**: Remember that in racemose inflorescence, the main axis does not terminate in a flower, allowing for continuous growth.

2. **Analyzing the Options**:
- **Option 1**: "The shoot axis shows definite growth."
- This is incorrect because the shoot axis in racemose inflorescence exhibits indefinite growth.

**Hint**: Look for terms like "definite" and "indefinite" when assessing growth patterns.

- **Option 2**: "Flowers are born in basipetal succession."
- This is incorrect. In basipetal succession, older flowers are at the base and younger flowers are at the top. This does not apply to racemose inflorescence.

**Hint**: Understand the difference between basipetal and acropetal succession.

- **Option 3**: "Flowers are born in acropetal succession."
- This is correct. In acropetal succession, younger flowers are at the top and older flowers are at the base, which is characteristic of racemose inflorescence.

**Hint**: Acropetal succession means that as you move up the axis, the flowers are younger.

- **Option 4**: "Older flowers are present towards the apex and younger flowers are present at the base."
- This is incorrect as it describes basipetal succession, which does not apply to racemose inflorescence.

**Hint**: Apex refers to the top of the plant; think about where older and younger flowers are located in relation to the apex.

3. **Conclusion**:
- The correct statement for racemose inflorescence is **Option 3: Flowers are born in acropetal succession**.

### Final Answer:
**The correct statement for racemose inflorescence is: Flowers are born in acropetal succession.**
