Will’s achenes–Are they alive?

Photos of the sheets of sticky notes containing achenes (Echinacea fruits) that Will dissected at the U of Minnesota and that Jared will x-ray at the Chicago Botanic Garden this afternoon.

Will used freeze-dried pollen to pollinate the flowers that produced these fruits. During the summer styles of those flowers shriveled shortly after Will deposited pollen, providing evidence that the pollen was still alive. More backstory.

Do these these achenes contain embryos? We’ll find out this afternoon.
