Answer 2

Answer:

The right answer is (4)Archegonium.

Explanation:

• Ferns and horsetails are pteridophytes.
• Pteridophytes are terrestrial plants in which vascular tissues like xylem and phloem are present.
• Sporophytes are present in pteridophytes and inside sporophytes are sporangia which produce spores.
• Spore is formed by the process of meiosis and when spores germinate gametophytes are produced.
• The gametophytes in pteridophytes are called prothallus.
• The male and female sex organs are present in the gametophytes.
• The male sex organ is called antheridia and it produces male gametes called antherozoids which are released from the antheridia to the mouth of archegonia.
• The female sex organ is called archegonia where the female gametes that are eggs are present.
• The fusion of male and female gametes results in the formation of a zygote.
• Therefore, in pteridophytes, the fusion of gametes takes place in Archegonium.
