The Smallest Life Around Us

    Tiny plants and animals live all around us.We cannot see them because they are so small,but they are everywhere. They live in the soil,in the air,and in rivers and oceans.They grow on mountains and in caves.Some live in the ice at the north and south poles; some live where it is very hot.They are found throughout cities and in the country. They grow on other plants and animals.Some are even living on you,on your skin,hair,and inside your body,in your mouth,nose,and all through your body.

    These tiny plants and animals are called microbes.The word microbe is made from two other words:micro,meaning small,and bios,meaning life.So,microbe means small life.

    Microbes have been on earth for a very long time.They may have been the first forms of life to be alive.Today there are more microbes in the world than all other living things.

    People did not know microbes had existed(存在) long.They were too small for them to see.But people did see many changes in their world﹣important changes.And they did not know what caused them.They saw food that they kept too long change color and begin to smell bad.They saw cuts and wounds grow red and painful and become worse. They saw old plants and leaves and trees crumble apart on the forest floor and disappear into the soil.Such changes were a natural part of the world,but people did not understand them.They did not know these changes were evidence(证据) of tiny plants and animals growing all around them.

    We usually think that plants always stay quiet and never speak. Grass doesn't cry when you cut it; flowers don't shout when they're picked. But this view of the world couldn't be more wrong. Plants talk to each other all the time. Their language is one of chemicals.

    Over the years, scientists have found that different types of plants, from trees to tomatoes, send compounds(复合物)into the air to help neighboring plants. But exactly how plants receive and act on many of these signals is still a mystery.

    Scientists from Kyoto University in Japan looked at tomato plants that had been bitten by insects. To start out, they grew plants in two plastic bags connected by a tube(管子). One plant had been bitten by insects. The other was not bitten.

    They found that when insects bite plant leaves, the plants don't sit quietly. They send a chemical called "hexvic" into the air. Humans can't notice it, but these chemicals carry a smell that neighboring plants can notice. This way, neighboring plants realize the danger and begin to give off more "hexvic" to protect themselves.

    The same scientists continued their research by placing insects on the plants that had not been bitten. The plants were able to kill nearly 50 percent of the invaders, much more than their neighbor.

    It was surprising that the plants that had not been bitten didn't send the chemical until the received a warning message from their infested(受侵的)neighbor, the scientists said. These findings could be used to help farmers with the control of the insects which do harm to their plants.
