How does a fern look like?
Some look like tiny bunches of grapes , some look like a little brown purse, and others like a dome. Often the sporangium starts out light green and as it ripens, turns dark brown. Ferns spores develop into what scientists call “gametophytes”, which usually look flat, green and spongy.
