Which of the following is incorrect ?

Options

A. Double fertilization is characteristics of angiosperm.
B. Double fertilization was discovered by Nawaschin.
C. Pollen tube shown apical growth and chemotropic movement.
D. Basal part of ovule is called as micropyle.

Answer

To solve the question "Which of the following is incorrect?", we need to analyze each of the provided statements to determine which one is false.

### Step-by-Step Solution:

1. **Evaluate Statement 1**:
- **Statement**: "Double fertilization is the characteristic of angiosperms."
- **Analysis**: This statement is correct. Double fertilization is indeed a characteristic feature of angiosperms (flowering plants).

2. **Evaluate Statement 2**:
- **Statement**: "Double fertilization was discovered by Nuwashchin."
- **Analysis**: This statement is also correct. Nuwashchin discovered double fertilization in 1898 in Liliaceous plants.

3. **Evaluate Statement 3**:
- **Statement**: "Pollen tube shows apical growth and chemotropic movement."
- **Analysis**: This statement is correct. The pollen tube does exhibit apical growth and moves towards chemical signals (chemotropic movement).

4. **Evaluate Statement 4**:
- **Statement**: "The basal part of the ovule is called micropyle."
- **Analysis**: This statement is incorrect. The basal part of the ovule is actually called the chalaza, while the micropyle is the opening at the opposite end of the ovule.

### Conclusion:
Based on the evaluations, the incorrect statement is:
- **Option 4**: "The basal part of the ovule is called micropyle."

### Final Answer:
The answer to the question is **Option 4**.
