Experiment: Scientists used a Geiger counter to test radiation absorption in plant leaves covered with aluminum foil vs. uncovered ones.Observation: Covered leaves showed near-zero radiation exposure while uncovered ones absorbed detectable radiation.Question: What conclusion can be drawn?
Correct answer: A. Metallic surfaces can block radiation from reaching plant tissues.
- A. Metallic surfaces can block radiation from reaching plant tissues.
- B. All plant tissues reflect radiation.
- C. Radiation penetrates aluminum easily.
- D. Plants generate radiation internally.
Explanation
The correct answer is that metallic surfaces, like aluminum foil, can block radiation from reaching plant tissues. This conclusion is supported by the observation that covered leaves showed near-zero radiation exposure while uncovered leaves absorbed detectable radiation. The other options are incorrect as they do not align with the experimental results or logic.
