Select the incorrect statement regarding angiosperm

Options

A. Pollen grain is the first cell of male gametophyte
B. Megaspore is diploid
C. Megaspore is the first cell of female gametophyte
D. All of above.

Answer

To solve the question regarding which statement about angiosperms is incorrect, we can follow these steps:

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

### Step 2: Evaluate the First Statement
The first statement claims that "pollen grain is a first cell of male gametophyte."
- **Explanation**: Pollen grains are indeed the male gametophytes in angiosperms. They develop from microspores, which are produced by the microspore mother cell undergoing meiosis. Therefore, this statement is **correct**.

### Step 3: Evaluate the Second Statement
The second statement claims that "megaspore is diploid."
- **Explanation**: The megaspore is produced from a diploid megaspore mother cell through meiosis, resulting in haploid megaspores. Therefore, this statement is **incorrect**.

### Step 4: Evaluate the Third Statement
The third statement claims that "megaspore is the first cell of our male gametophyte."
- **Explanation**: This statement is misleading because the megaspore is part of the female gametophyte (embryo sac) and not the male gametophyte. However, since the question is about identifying the incorrect statement, we have already established that the second statement is incorrect.

### Conclusion
Based on the evaluation, the incorrect statement regarding angiosperms is:
- **Answer**: The second statement: "megaspore is diploid."
