Biology Practice: The Flower (Mock Test 4 - Expert/Experimental Logic)
1. In an experiment, if the anthers of a bisexual flower are removed before they mature (Emasculation), what is the most likely goal?
2. A student covers a flower with a plastic bag during a pollination experiment. What is the logic behind this "Bagging" technique?
3. If a flower has a very long, narrow corolla tube, which type of pollinator is it most logically adapted for?
4. Observation: A flower is large, white, and emits a strong scent only at night. What can you conclude about its pollinator?
5. In a laboratory test, pollen grains fail to germinate on the stigma of a different species. This is an example of:
6. If you observe a flower with feathery stigmas hanging outside the petals, it is most likely pollinated by:
7. A flower is found to have "Protandry." What does this experimental term mean?
8. What is the clinical significance of "Hay Fever" in humans related to flowers?
9. If a fruit contains 50 seeds, what is the minimum number of pollen grains that must have successfully germinated?
10. Why do seeds often enter a state of "Dormancy" after dispersal?
11. A "Zygomorphous" flower is one that can be divided into two equal halves by:
12. Experimental data shows that flowers with bright red colors but no scent are often pollinated by:
13. In the condition of "Herko-gamy," a mechanical barrier prevents:
14. Which chemical is often used in labs to stimulate the artificial germination of pollen grains in a sugar solution?
15. The term "Cleistogamy" refers to flowers that:
16. If an ovary has many ovules, the resulting fruit will have:
17. A "Superior Ovary" is one that is placed:
18. The "Pappus" is a modification of sepals in some flowers used for:
19. "Parthenocarpy" is a logical biological process where:
20. In an experiment, applying "Auxins" to an unpollinated flower can induce:
