Why do plants get fungus?

Can plants cry?

When injured, plants can cry for help via a chemical phone call to the roots. If under attack by a pathogen, such as disease-causing bacteria, a plant’s leaf can send out an S.O.S. to the roots for help, and the roots will then secrete an acid that brings beneficial bacteria to the rescue, scientists announced today.
