Which came first, the plant or the seed?

Forget the chicken and the egg conundrum, this botanical argument has a resolution covering millions of years.

The earliest fossils of complex land plants date from around 470 million years ago. They resembled liverworts – a kind of simple moss – and reproduced by releasing spores, which were carried away when it rained.
Spores contain a single cell, whereas a seed contains a multicellular, fertilized embryo that is protected from drying out by a tough coat. These extra features took another 150 million years to evolve, whereupon the first seed-bearing plants emerged. So plants came first, by a long way.

Fascinating, It’s a great picture too of the sprouting corn.
I find the info about seeds, plants, rocks, and soil very interesting!
