Most plants in the world spread their seeds by the wind and by bee pollination. But there are also quite a few seeds that are pedestrians. Seeds that stay on the ground and have to fend for themselves completely and start wandering to find a suitable place to germinate, and of course manage to do all this without being eaten - and they do it in a fascinating variety of ways.

How do they migrate? Does a seed have legs? How far does sperm travel? We talked about all these things, and more, with Prof. Rebecca Elbaum, the guest in this episode of HUJICAST.
