Question
In which group of plants do microspores and megaspores develop into separate male and female gametophytes?
Explanation
Some pteridophytes (e.g., Selaginella, Salvinia) show heterospory, where microspores form male gametophytes and megaspores form female gametophytes. All gymnosperms are also heterosporous. Hence, the correct answer is "Pteridophytes and Gymnosperms".
