According to a recent study, plants are able to make intelligent decisions. They are a lot 1. (smart) than we thought. Scientists have discovered that the pea plant can make decisions on how 2. (survive) best, even though it does not have a brain. Researchers grew several pea plants that had their roots 3. (separate) between two pots. Each pot contained different amount of nutrients. One pot always had the same amount, 4.the other pot varied between a lot and a little. The plants turned out to be 5. (amaze) consistent（一致的）at turning their roots to the pot with the most nutrients.

Researcher Alex Kacelnik says the experiment raises a question, not about plants, 6. about animals and humans. He wonders whether the pea plant is more efficient in using its limited resources about 7. (make) decisions than humans. He says, “We have a very wonderful brain, but maybe most of the time we’re not using 8..” Professor Kacelnik does not think that pea plants are intelligent in the human sense, but that they exhibit complex 9. (behave) to efficiently take advantage of natural opportunities. It will be interesting to see how our lives would be different if we 10. (adopt) similar strategies.
