Read the following statements and select the correct option.
Assertion : In gymnosperms, endosperm is formed before fertilization and is haploid.
Reason : In angiosperms, endosperm is formed after fertilization and is diploid.

Options

A. Both statements 1 and 2 are correct and
statement 2 is the correct explanation of statement
1.
B. Both statements 1 and 2 are correct but
statement 2 is not the correct explanation of
statement 1.
C. Statement 1 is correct and statement 2 is
D. Both statements 1 and 2 are incorrect

Answer

To solve the question, we need to analyze both the assertion and the reason provided in the statements.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that in gymnosperms, the endosperm is formed before fertilization and is haploid.
- In gymnosperms, the endosperm develops from the female gametophyte, which is indeed haploid. Therefore, this part of the assertion is correct.

2. **Understanding the Reason**:
- The reason states that in angiosperms, the endosperm is formed after fertilization and is diploid.
- In angiosperms, the endosperm is formed after fertilization, but it is not diploid; it is actually triploid. This is because the endosperm is formed from the fusion of one sperm cell with two polar nuclei (which are diploid), resulting in a triploid endosperm. Thus, this part of the reason is incorrect.

3. **Conclusion**:
- Since the assertion is correct and the reason is incorrect, we can conclude that the correct option corresponds to this situation.

4. **Selecting the Correct Option**:
- Based on the analysis, the correct answer is that the assertion is true and the reason is false. Therefore, the correct option is option 3.

### Final Answer:
The correct option is: Assertion is true, Reason is false (Option 3).
