Turns out, the thale cress actually produces some mustard oils and sends them through the leaves to deter predators (the oils are mildly toxic when ingested). And the study showed that when the plants felt or heard the caterpillar-munching vibrations, they sent out extra mustard oils into the leaves. When they felt or heard other vibrations? Nothing. It’s a far more dynamic defense than scientists had realized: the plant is more aware of its surroundings and able to respond than expected.
That's interesting. And we know plants have passive defense mechanisms too; some have "anti-nutrients" designed to deter predators. The poisons are so mild it can take decades to weaken the animal. Some predators build up the ability to break down those anti-nutrients over time. |

There are radish families that grow into the forms of giant penises so humans don't eat them. |

I tried to explain to dad that I couldn't stand the screaming of the grass when he wanted me to mow the lawn .... |
