Self pollination is not possible in ________ ?
Correct answer: D. both A and B Educational Resources
- A. Dioecious plants
- B. Pawpaw
- C. Flowers
- D. both A and B Educational Resources
Explanation
Self-pollination cannot occur in dioecious plants because male and female flowers are present on separate plants; pawpaw is a commonly cited dioecious plant. The likely trap is c, because the word “flowers” is too general, whereas many flowers are bisexual and can self-pollinate.
