Options

A. It is a modified shoot
B. It is a reproductive unit of angiosperms
C. It is trimerous in potato family
D. Calyx and corolla are accessory whorls of a flower

Answer

To solve the question regarding the statements about flowers, we will analyze each statement provided and determine which one is incorrect.

### Step-by-Step Solution:

1. **Identify the Characteristics of Flowers**:
- Flowers are the reproductive structures of angiosperms (flowering plants).
- They are modified shoots that contain reproductive organs.

2. **Evaluate Each Statement**:
- **Statement 1**: "Flowers are a modified shoot."
- This statement is **correct**. Flowers develop from the shoot apical meristem and are indeed modified shoots.

- **Statement 2**: "Flowers act as a reproductive unit."
- This statement is **correct**. Flowers contain the reproductive organs (stamens and carpels) and are involved in the process of fertilization and reproduction.

- **Statement 3**: "It is trimerous in potato family."
- This statement is **incorrect**. The term "trimerous" refers to flowers that have parts in multiples of three, which is characteristic of monocots. However, the potato (Solanum tuberosum) belongs to the Solanaceae family, which typically has flowers with five parts (pentamerous), not three.

- **Statement 4**: "Calyx and corolla are accessory roles of the flower."
- This statement is **correct**. The calyx (sepals) and corolla (petals) serve as accessory structures that protect the reproductive parts and attract pollinators.

3. **Conclusion**:
- The statement that is incorrect is the one regarding the potato family being trimerous. Therefore, the answer to the question is that the statement about the potato family is the only incorrect one.

### Final Answer:
The incorrect statement is: "It is trimerous in potato family."
