Ferns and pine trees can be classified as different based on whether they have seeds.

Ferns are non-seed plants and do not produce seeds. They reproduce by spores.

Pine trees, on the other hand, are seed-producing plants. They have cones that contain seeds, which are dispersed to reproduce new plants.

So, based on this characteristic, ferns and pine trees can be classified as different organisms from each other.
