The term “plant neurobiology” was around the notion that some aspects of plant behavior could be to intelligence in animals. plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that consciousness, researchers previously reported.
But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it so greatly from that of animals that so-called of plants' intelligence is inconclusive, the authors wrote.
Beginning in 2006, some scientists have that plants possess neuron-like cells that interact with hormones and neurotransmitters, “a plant nervous system, to that in animals,” said lead study author Lincoln Taiz. “They claimed that plants have 'brain-like command centers' at their root tips.”

- A、list
- B、level
- C、label
- D、load
题目解答
答案
解析
问题涉及对植物是否具有意识的讨论。文章提到,植物神经生物学的概念在2000年代初开始流行,但后来有新的观点认为,植物的生物学与动物的生物学差异很大,因此关于植物智能的说法是不确定的。
步骤 2:分析选项
A、list(列表):与上下文无关。
B、level(水平):与上下文中的“植物的智能”相关,表示程度或水平。
C、label(标签):与上下文无关。
D、load(负载):与上下文无关。
步骤 3:选择正确答案
根据上下文,正确答案是B,因为“level”可以表示植物智能的程度或水平,符合文章的讨论内容。
