This is like a warning, or a call for help: “I'm being attacked!” When another bean plant detects the chemicals from its injured neighbour, it starts to release its own, different chemicals. Some of these chemicals drive insects away. Others attract insects - the wasps! The wasps kill the insects that are eating the bean plants. Scientists hope to learn more about this plant warning system, so that we can use it to grow crops without pesticides. bean plants.

What is its function? 修辞手法 Personification means giving human characteristics to something that is not human. By using human characteristics to describe an object, animal or even a place, personificaton can make descriptions more vivid. 25 It has been known for some time that plants use chemicals to communicate with each other. This happens when a plant, say a bean plant, gets attacked by insects. The plant releases tiny amounts of chemicals from the leaves that are being eaten. This is like a warning, or a call for help: “I'm being attacked!” When another bean plant detects the chemicals from its injured neighbour, it starts to release its own, different chemicals. Some of these chemicals drive insects away. Others attract insects - the wasps! The wasps kill the insects that are eating theIt has beenetwork links the roots of different plants to each other. Using the wood wide web, plants can share information and even food with each other. For example, some pine trees can send food to smaller pine trees to help them grow. But just like our own Internet, the wood wide web has its own version of “cybercrime”. Plants can steal food from each other, or spread poisons to attack other plants. Perhaps one day scientists will learn how to create a “firewall” to help prevent these attacks within the wood wide web. n known for some time that plants use chemicals to communicate with each other.
