All the given statements w.r.t. flower are correct, expect

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 which statement about flowers is incorrect, we can follow these steps:

### Step 1: Analyze the Statements
We need to evaluate each statement provided about flowers to determine which one is incorrect.

### Step 2: Evaluate the First Statement
The first statement claims that a flower is a modified shoot. This is a correct statement. Flowers do indeed arise from the modification of a shoot, where the vegetative parts are transformed into reproductive structures.

### Step 3: Evaluate the Second Statement
The second statement states that a flower is a reproductive unit of angiosperms. This is also correct. Flowers are the reproductive structures of angiosperms, containing both male (stamens) and female (pistils) parts, facilitating fertilization and seed production.

### Step 4: Evaluate the Third Statement
The third statement claims that flowers in the potato family (Solanaceae) are trimerous. This statement is incorrect. Flowers in the potato family are actually pentamerous, meaning they typically have five petals, not three.

### Step 5: Evaluate the Fourth Statement
The fourth statement mentions that calyx and corolla are accessory whorls of a flower. This is correct. The calyx (sepals) and corolla (petals) are indeed accessory structures that protect the reproductive parts and attract pollinators.

### Conclusion
Based on the evaluations, the third statement about the potato family being trimerous is the incorrect one.

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