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 it 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(蘭葉草) 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(毛蟲) , the other members of the network are warned via an internal signal. Once warned the intact(完好無損的) plants strengthen their chemical and mechanicaicl(機體的)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,

According to a legend, a young man while roaming the desert came across a spring of delicious crystal-clear water.The water was so sweet, he 36 his leather canteen so he could bring some 37 to a tribal elder who had been his teacher.

I think we understand this lesson best when we receive 48 gifts of love from young children. 49 it's a ceramic tray or a macaroni bracelet, the 50 and proper response is 51 and expressed thankfulness because we love the idea within the gift.
Gratitude doesn't always come naturally. 52 , most children and many adults value only the thing given 53 the feeling embodied in it.We should remind ourselves and 54 our children about the beauty and purity of feelings and expressions of gratitude. 55 , gifts from the heart are really gifts of the heart.
