02.05 - How Plants Poop

Episode description:

A rose by any other name would smell as sweet. But that rose would still have to poop. Well, sort of. While we might not think of plants as producing poop, they’re not free of the inefficiencies of a metabolic life. In the green world, life is anything but easy in, easy out, and in this episode, we’ll look at the many ways that plants “poop” or at least how they deal with the things they’d rather not leave lying around. This is the Single Acorn Podscat.
