Think again!Plants are able to do some pretty awesome things that you’re probably totally unaware of.Researchers have discovered that plants have the ability to communicate with an underground network made up of fungus (真菌) , which serves the plants in many ways. Tomatoplants use the fungus web to warn each other of their own unhealthy conditions. Trees connected through the fungus network could move nutrients (养分) to and from each other. It isbelieved that larger trees move nutrients to smaller ones to help them to survive.Not only that, but they can also damage unwelcome plants by spreading poisonouschemicals through the fungus. It sounds like the plant world had the Internet before we did.Some plants have a rather impressive line of defense against being eaten. When sensingthey are being swallowed, they give off a chemical into the air that attracts the insect’enemy. The enemy attacks the bug, thus saving the plants. This is basically the plant kingdomversion of getting your older brother to beat up that kid who steals your lunch money.You might be aware that humans and animals have an internal clock. But did you know thatplants also have this clock? This means they can prepare for certain times of day just like we do.Is it because they can react to light at sunrise? In a study, scientists found that plants use thesugars they produce to keep time, which help to regulate the genes responsible for the plantpetunias (矮牵牛) is just as valid as ―wake upown internal clock.
