Explanation:

Heterospory in Pteridophytes:

Such Pteridophytes are known asheterosporous and the phenomenon is known asheterospory. The two types of spores are microspores and megaspores. Microspores are smaller in size and develop into the male gametophyte while the megaspores are large and develop into female gametophyte.

EXAMPLES✅

Heterospory is the phenomenon of formation of two types of spores, i.e., smaller microspore and larger megaspore. ... Examples of heterosporyare Selaginella, Salvinia and Marsilea, etc.

Answer 2

hey mate...

here is your answer...

Homosporous pteridophytes are the pteridophytes which produce only one type of spores. The germination of these spores produces a bisexual gametophyte. On the other hand, heterosporous pteridophytes are the pteridophytes which produce two types of spores: microspores and megaspores.
