Humans need sleep to survive, but do plants doze off too? In this episode, we’ll look into how plants rest. Turns out humans and plants aren’t all that different! We’ll hear about how we share a common ancestor, way, way back in history. We’ll also learn how plants and people have little built-in clocks that tell us when it’s day and night! Oh, and Sanden parties with his plant pals and we guess an all-new Mystery Sound. This episode was sponsored by: Indeed (Indeed.com/BRAINS - Terms and conditions apply.
