Are gymnosperms heterosporous?

Answered

Yes, gymnosperms are heterosporous. They produce two distinct types of spores: microspores (male) and megaspores (female). Microspores develop into male gametophytes (pollen grains), while megaspores develop into female gametophytes within ovules. This differentiation facilitates sexual reproduction and is a key feature distinguishing seed plants from their homosporous ancestors.
