A Those plants which produce seeds, without the formation of fruits are called Gymnosperms.
R Endosperm is triploid in Angiosperms

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

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

### Step 1: Understand the Assertion
The assertion states: "Those plants which produce seeds, without the formation of fruits are called Gymnosperms."

- **Explanation**: Gymnosperms are indeed a group of plants that produce seeds that are not enclosed within a fruit. This is a defining characteristic of gymnosperms. The seeds develop from ovules, which are not enclosed in an ovary, hence they are termed "naked seeds."

### Step 2: Understand the Reason
The reason states: "Endosperm is triploid in Angiosperms."

- **Explanation**: In angiosperms (flowering plants), the endosperm is formed as a result of a process called double fertilization. One male gamete fuses with the egg cell to form the zygote, while the other male gamete fuses with two polar nuclei to form the triploid endosperm. Therefore, this statement is also true.

### Step 3: Determine the Relationship Between Assertion and Reason
Now, we need to determine if the reason provided correctly explains the assertion.

- **Analysis**: While both statements are true, they refer to different groups of plants. The assertion is about gymnosperms, while the reason pertains to angiosperms. The reason does not explain why gymnosperms produce naked seeds.

### Conclusion
Based on the analysis:
- Both the assertion and reason are correct.
- However, the reason does not serve as a correct explanation for the assertion.

Thus, the correct answer is: **Both assertion and reason are correct, but reason is not the correct explanation of assertion.**
