Select the incorrect statement:

Options

A. Flowers are morphological and embryological marvels and sites of sexual reproduction.
B. Several hormonal and structural changes take place prior to development of floral primordium
C. The distal end of the filament is attached to the thalamus or the petal of the flower.
D. Flowers are objects of aesthetic, ornamental, social, religious and cultural value

Answer

To solve the question of identifying the incorrect statement, we can follow these steps:

### Step 1: Analyze Each Statement
We will go through each statement one by one to determine if they are true or false.

### Step 2: Evaluate the First Statement
**Statement 1:** "Flowers are the morphological and embryological marbles and sites of sexual reproduction."
- **Analysis:** This statement is true. Flowers are indeed the sites of sexual reproduction in angiosperms and have significant morphological and embryological importance.

### Step 3: Evaluate the Second Statement
**Statement 2:** "Several hormonal and structural changes take place prior to the development of the floral primordia."
- **Analysis:** This statement is also true. The development of floral primordia is influenced by various hormones, including Florigen, and involves structural changes.

### Step 4: Evaluate the Third Statement
**Statement 3:** "The distal end of the filament is attached to the thalamus or petal of the flower."
- **Analysis:** This statement is false. The distal end of the filament actually has the anther, which is where pollen is produced. The proximal end of the filament is what attaches to the thalamus or petals.

### Step 5: Evaluate the Fourth Statement
**Statement 4:** "Flowers are objects of aesthetic, ornamental, social, religious, and cultural value."
- **Analysis:** This statement is true. Flowers do hold significant aesthetic and cultural value in various societies.

### Step 6: Conclusion
Based on the evaluations, the incorrect statement is:
- **Incorrect Statement:** "The distal end of the filament is attached to the thalamus or petal of the flower."

### Final Answer
The answer to the question is the third statement.
