Can plants talk? Modern research has found that they do communicate with each other.
It has been known for some time that plants use special smells to communicate with each other. This happens when a plant gets hurt by insects. The plant gives out a special smell from the leaves that are being eaten. This is like a warning or a call for help. When another plant gets the smell, it starts to give out its own. Some of these smells drive insects away. Others make the wasps（黄蜂）come! The wasps kill the insects that are eating the plants. Scientists hope to learn more about the plant warning, so that we can use it to grow more fruit and vegetables.
More surprisingly, plants also use sound to communicate. People can't hear these sounds, but plants are making them. Some plants， such as fruit and vegetables， make noises with their roots （根）. Some trees make noises when there is not enough water.
Most surprisingly of all, plants have an amazing way of communication that can connect nearly every plant in a forest. Scientists call this "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. UJsing the wood wide web, plants can share information and even food with each other. However, it may lead to bad results. Plants may use it to steal food from each other, or spread smells to kill or hurt other plants. Perhaps one day scientists will learn how to create a "firewall" to help stop such hurt within the wood wide web.
Scientists are learning more about the secret ways in which plants talk to each other. Maybe one day we will know enough about plant communication to be able to "talk" with them ourselves.
