In pteridophytes, fusion of gametes takes place in
1 External medium
2 Antheridium
3 Antherozoids
4 Archegonium
Explanation:
The male gametes from the antheridia are released to the mouth of archegonium. Fusionof male gamete with the egg takes placee in the archegonium resulting in the formation of zygote.
