Worked practice questions
Pollen moving to another flower of the same plant is called
- autogamy
- xenogamy
- geitonogamy
- cleistogamy
Show answer and solution
Correct answer: C. geitonogamy
This is geitonogamy; it needs a pollinator yet is genetically like self-pollination.
Which pollination brings genetically different pollen to the stigma?
- Autogamy
- Cleistogamy
- Geitonogamy
- Xenogamy
Show answer and solution
Correct answer: D. Xenogamy
Xenogamy moves pollen between different plants, giving genetically unlike pollen.
