The smell of freshly-cut grass is actually a plant distress call
attacked, plants release airborne chemical compounds. Now scientists say
plants can use these compounds almost like language, notifying nearby
creatures who can "rescue" them from insect attacks.
A group of German scientists studying a wild tobacco plant noticed
that the compounds it released - called green leaf volatiles or GLVs -
were very specific. When the plants were infested by caterpillars, the
plants released a distress GLV that attracted predatory bugs who like to
eat the caterpillars in question.....
....I think what's most interesting about this study is the way it suggests
that plants have a rudimentary form of language based on releasing these
chemical compounds. These tobacco plants have the ability to modulate
the signals they send out, depending on the kind of attack they're
suffering. Combine this discovery with the one a few weeks ago, that
plants are able to perform simple computations,
and it's clear that the average person underestimates how much plants
are dynamically engaged with their environments. It's interesting to
imagine plants as having truly alien forms of consciousness and
communication - different from animals' minds, but sometimes performing
