I believe that animals possess greater intelligence than most people think. But plants? I've never considered the possibility of plant intelligence. The idea seems absurd.

Yet I've had friends argue that plant intelligence might exist. "What are the differences between plants and animals?" they ask, and then they argue about certain species that seem to share the intelligence of both plants and animals.

New research suggests that plants communicate via "networks". Plant communication is not idea, and cannot indicate that its is a kind of intelligence, but it is still interesting.

Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen shows that plants have their own chat systems that they can use to warn each other. Therefore plants are not boring and passive organisms that just stand there waiting to be cut down or eaten up. Many plants form internal communication networks and are able to exchange information networks and are able to exchange information efficiently.

Many herbal plants such as strawberries and clovers (三叶草)naturally form networks.

Individual plants remain connected with each other for a certain period of time by means of runners (plant stems that grow along the ground and put down roots to form new plants). These connections enable the plants to share information with each other via internal channels. They are therefore very similar to computer networks. But what do plants chat to each other about?

Recently Stuefer and his colleagues were the first to prove that clover plants warn each other via the network links if danger is nearby . If one of the plants is attacked by caterpillars (毛虫)，the other members of the network are warned via an internal signal. Once warned the intact (完好无损的)plants strengthen their chemical and mechanical (机体的)resistance so that they are less attractive to advancing caterpillars. Thanks to this early warning system, the plants can stay one step ahead of their attackers. The research has shown that this significantly limits the damage to the plants.

Again, I don't believe this reflects intelligence, but it's is certainly fascinating.

--- “I’ve never eaten a hamburger.”

--- “_________ have I.”

Work is a part of living —my grandparents understood that. They lived and worked on a farm that has been in my family for 150 years. They raised chickens for eggs , pigs and cattle for meat . Cows were kept for milk and the cream, from which Grandma made butter and cheese. What little yard they had became a garden.
The Depression, therefore, didn’t make much change in their lives. But it did bring an unending flow of men out of work, drifting from job to job, to the farm. The first to show up at the door of the kitchen was a man in rags. He took off his hat and quietly explained that he hadn’t eaten for a while. Grandpa stood watching him a bit , then said , “There’s a stack of firewood against the fence behind the barn (谷仓). I’ve been needing to get it moved to the other side of the fence . You have just about enough time to finish the job before lunch .”
Grandma said a surprising thing happened. The man got a shine in his eyes and he hurried to the barn at once. She set another place at the table and made an apple pie. During lunch, the stranger didn’t say much, but when he left, his shoulders had straightened. “Nothing ruins a man like losing his self-respect,” Grandpa later told me.
Soon after, another man showed up asking for a meal. This one was dressed in a suit and carried a small old suitcase. Grandpa came out when he heard voices. He looked at the man and then offered a handshake.” There is a stack of firewood along the fence down behind the barn I’ve been meaning to get it moved. It’d sure be a help to me . And we’d be pleased to have you stay for lunch.” The fellow set his suitcase aside and neatly laid his coat on top. Then he set off to work.
Grandma says she doesn’t remember how many strangers they shared a meal with during those Depression days-or how many times that stack of wood got moved.
