Question

Motile sperm cells swim through an external film of water to reach female gametes mail of the following groups except for:

• A. Pteridophyta
• B. Spermatophyta
• C. Lycopodiophyta
• D. Bryophyta

Answer 1

Answer: (B)

Spermatophyta

In Pteridophyta, antherozoids can get transferred to the archegonia which are the female sex organs, only in the presence of water. Lycopodium is a subdivision of Pteridophyta and reproduction in Lycopodium, therefore, occurs in a similar manner. Bryophytes also require water to transfer the sperm from antheridia to the egg in the archegonia. However, in Spermatophyta (seed plants) water is not required for the transfer of gametes.

So, the correct option is 'Spermatophyta'.
