Gymnosperms have archegonia but no antheridia. The plants of this division are heterosporous. While the microspores or pollen grains produce the male gametophyte, the single megaspore within megasporangium (nucellus) develops into a female gametophyte, that bears two or more archegonia or female sex-organs. Also, there is no antheridium in which the sperm are produced.
