A: Pollination with the help of a pollen tube is called porogamy.
R: Pollination occurs before meiosis of pollen mother cells.

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 assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
- **Assertion (A)**: "Pollination with the help of a pollen tube is called porogamy."
- **Explanation**: The assertion states that pollination involving a pollen tube is termed "porogamy." However, this is incorrect. The correct term for pollination that involves a pollen tube is "siphonogamy." Porogamy specifically refers to the entry of the pollen tube through the micropyle of the ovule, while siphonogamy refers to the mechanism of pollen tube growth and fertilization.

### Step 2: Analyze the Reason
- **Reason (R)**: "Pollination occurs before meiosis of pollen mother cells."
- **Explanation**: The reason states that pollination occurs before meiosis of the pollen mother cells. This statement is also incorrect. Pollination is the transfer of pollen grains from the anther to the stigma and can only occur after meiosis has taken place in the pollen mother cells. Meiosis results in the formation of haploid pollen grains, which are then involved in the process of pollination.

### Step 3: Conclusion
- Both the assertion and the reason are false. Therefore, the correct answer to the question is that both statements are incorrect.

### Final Answer
Both the assertion and the reason are false statements.
