Select the incorrect statement.

Options

A. Typical angiospermic anther is tetrasporngiate.
B. Usually one microspore mother cell gives rise to two functional microspore.
C. Tapetal cells have two or more nuclei.
D. Sporopollenin in exine is one of the most resistant material.

Answer

To solve the question of selecting the incorrect statement, we will analyze each statement one by one based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Statement 1: Typical angiospermic anther is Tetrasporangiate.**
- **Explanation:** Angiospermic anthers are indeed tetrasporangiate, meaning they contain four microsporangia. This is a correct statement as it accurately describes the structure of the anther in flowering plants.

2. **Statement 2: Usually one microspore mother cell gives rise to two functional microspores.**
- **Explanation:** This statement is incorrect. In reality, one microspore mother cell undergoes meiosis to produce four microspores, which are arranged in tetrads. Therefore, this statement is false.

3. **Statement 3: Tapetum cells have two or more nuclei.**
- **Explanation:** This statement is correct. The tapetum is the inner layer of the anther and is known to be multi-nucleated, providing nourishment to the developing pollen grains.

4. **Statement 4: Sporopolynin in enzyme is one of the most resistant materials.**
- **Explanation:** This statement is also correct. Sporopolynin is indeed a highly resistant organic material found in the outer layer of pollen grains, capable of withstanding extreme conditions.

### Conclusion:
The incorrect statement is **Statement 2: Usually one microspore mother cell gives rise to two functional microspores.**
