Mosses and ferns are homosporous, meaning that they produce only one type of spore. all seed plants are heterosporous, meaning that they produce and spores.

The correct answer will be-Mega and microspores.

Explanation:

The primitive group of plants which evolved during the early period of evolution in the history of evolution of plants like Bryophytes and Pteridophytes reproduced by the production of the single type of spores and are called homosporous plants.

The Seed bearing plants evolved later and produced two types of spores that are the megaspore which develops into female gametophyte and the microspores which develop into male gametophyte and are known as the heterosporous plants.

Thus, Mega and microspores are the correct answer.
