What are some key characteristics to look for in brophyte, fern, gymnosperms, and angiosperms?

[Gabby]

I know angiosperms have flowers or fruit. Bryophyte is.. well, moss. Gymnosperms are usually trees (like pine trees) but what how can I tell fern is fern in contrast to the others?

THANK YOU so much ahead of time for all replies!

 

[For Prose]

They key is to determine how they reproduce. For example, you can look for sporangia on the underside of a fern leaf. Also, indicative to ferns are usually fronds. I am unaware if evidence of a frond is exact proof of a fern though.

 

Can you point out specifically what sorts of differences you are looking for?
