Microspores vs Megaspores Microspores and megaspores are sexual spores produced by vascular plants (some Pteridophytes and all Gymnosperms and Angiosperms) for sexual reproduction. Both microspores and megaspores on germination produce the respective gametophytic generations. The gametophytes on maturation produce sex organs and gametes to establish the fertilization and thus to […]

These two types of spore differ in their formation, structure and most importantly its functions and sexuality. In Pteridophytes, these […]
