Plants are not unlike humans. They can talk to each other and even call in reinforcements when the going gets tough.
Who says so? Australian gardener Don Burke and Australian National University chemistry Professor Ben Selinger, in reviewing research on plants over the past 10 years, have come to the conclusion that many plants have human qualities.
They say plants can communicate with each other by using a range of chemical signals.
"If a plant muncher such as a caterpillar or even a koala starts chewing on a plant, the plant will start sending chemicals to its leaves in an effort to repel the chewer," Mr Burke said.
"Nearby plants will also start emitting these same chemicals, anticipating that they'll also be attacked."
