Question

Given below are two statements:
Statement I: Bisexual flowers promote self-pollination.
Statement II: Self-incompatibility and male-sterility prevent self-pollination.

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

Bisexual = Together (Promotes self); Incompatibility = Rejection (Prevents self).

Answer 1

The Correct Option is A

Step 1: Concept
Plants have evolved various mechanisms to either ensure or prevent self-pollination (autogamy).

Step 2: Meaning
Bisexual flowers contain both male and female reproductive organs in close proximity.

Step 3: Analysis
Having both organs in one flower naturally increases the likelihood of self-pollination. Conversely, genetic barriers like self-incompatibility or functional barriers like male sterility are evolved strategies to force cross-pollination.

Step 4: Conclusion
Both statements accurately describe the biological factors influencing pollination types. Final Answer: (A)
