Can plants talk? Modern research has found something amazing: they do communicate with each other through certain “language”.

It has been known for some time that plants use chemicals (化学物质) to communicate with each other. This happens when a plant gets attacked (攻击) by insects. The plant gives out chemicals from the leaves that are being eaten. This is like a warning, or a call for help: “I’m being attacked!” When another plant gets the chemicals, it starts to give out its own, different chemicals. Some of these chemicals drive insects away. Others attract (吸引) the wasps (黄蜂)! The wasps kill the insects that are eating the plants. Scientists hope to learn more about this plant warning system (系统), so that we can use it to grow more crops.

More surprisingly, plants also use sound to communicate. People can’t hear these sounds; but plants are making them. Some plants make noises with their roots.

Most surprisingly of all, plants have an amazing system of communication that can connect nearly every plant in a forest. Scientists call this system the “wood wide web”. The wood wide web is connected underground by fungi (霉菌). It connects the roots of different plants to each other. It is in some ways similar to the Internet we use. Using the wood wide web, plants can share information and even food with each other. However, it may cause bad effects. Plants may use it to steal food from each other, or spread chemicals to attack other plants. Perhaps one day scientists will learn how to create a “firewall” to help stop these attacks within the wood wide web.
