Both will under appropriate conditions, produce a new plant.

Mostly, For some orchids lack an endosperm for food, and rely on a fungus to invade the minute seed, whereupon the orchid relies on the fungi to provide it with growth nutrients.

Ferns produce spores, from which an intermediate plant form develops, a prothallus, which in turn produces male and female parts. The sperm is motile (!) but needs the surface of the prothallus to be wet for this. The fertilized egg eventually develops into a new fern.
