Bryologist (a scientist that studies mosses, and their allies) gives a lecture to your biology class. In her lecture, she makes a reference to fern reproduction. She says, "Fern spores germinate into .

Fern spore germinates into prothallus.

Explanation:

Ferns are members of phylum pteridophyta, the vascular cryptogams.

These are first land plants which are known to have a distinct conducting system of xylem and phloem.

They reproduce by forming spores that germinates into a heart shaped gametophyte.

The heart shaped gametophyte has root like structure called rhizoids.

These rhizoids anchor the gametophyte to the substratum.
