Question

In pteridophytes, antherozoids released from antheridia reach the mouth of archegonia by: air/ water/ insect or birds

Answer 1

Answer:

Antherozoids of fern are sperical, coiled and multiflagellate. An antheridium or antherida is a haploid structure or organ producing and containing male gametes, called as antherozoids. It is present in the gametophyte phase of ferns. Antherozoids are motile male gametes or mature sexual reproductive cells, having a single set of unpaired chromosomes.

Answer 2

Answer:

In pteridophytes, antherozoids released from antheridia reach the mouth of archegonia by air.

Explanation:

• The male and female sex organs of pteridophytes are called archegonia and antheridia, respectively.
• The male gametes are liberated from the antheridia and transferred to the mouth of the archegonium through the transfer of antherozoids, which requires water.
• The zygote is created when the male gamete fuses with the egg inside the archegonium. A multicellular, we 11-differentiated sporophyte, which is the main phase of the pteridophytes, is then produced by the zygote.
• The transmission of antherozoids, the male gametes released from the antheridia to the mouth of the archegonium, requires water in ferns. Pteridophytes require water as a means of transporting gametes during fertilization.
