IPA: /ˈmaɪ.kroʊ.spɔːr/
KK: /ˈmaɪkroʊspɔr/
A type of spore that is smaller than the other type and develops into a male gametophyte in certain plants.
In some plants, the microspore develops into a male gametophyte, which is essential for reproduction.
Microspore → It is formed from "micro-" (from Greek "mikros", meaning small) and "spore" (from Greek "spora", meaning seed or sowing). The word "microspore" refers to a small spore, typically produced by certain plants and fungi.
Think of 'small' ('micro-') seeds ('spore') — that's why a microspore is a tiny spore.
