Which of the following is not correct w.r.t. pollen tube?

Options

A. It is glandular, secretory and absorptive
B. It has growth zone at its tip
C. Neither it secretes hydrolytic enzymes nor absorbs food from style
D. It was first reported by Italian mathematician Amici

Answer

To determine which statement regarding the pollen tube is incorrect, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Pollen Tube**:
- The pollen tube is an extension of the pollen grain that forms during the process of fertilization in flowering plants. It plays a crucial role in delivering sperm cells to the ovule.

2. **Evaluating the Options**:
- **Option 1**: "It is glandular, secretory, and absorptive."
- This statement is correct. The pollen tube has glandular properties, secreting substances that help in its growth and absorption of nutrients.

- **Option 2**: "It has a growth zone at its tip."
- This statement is also correct. The tip of the pollen tube contains a growth zone that allows it to elongate towards the ovule.

- **Option 3**: "It neither secretes hydrolytic enzymes nor absorbs food from the style."
- This statement is incorrect. The pollen tube does secrete hydrolytic enzymes to facilitate its entry into the ovule and absorbs nutrients from the style for its growth.

- **Option 4**: "It was first reported by an Italian mathematician."
- This statement is correct. The study of pollen tubes and their functions has historical ties to various scientists, including mathematicians.

3. **Identifying the Incorrect Statement**:
- Based on the evaluation, **Option 3** is the incorrect statement regarding the pollen tube.

### Final Answer:
The statement that is not correct with respect to the pollen tube is **Option 3**: "It neither secretes hydrolytic enzymes nor absorbs food from the style."
