Question

Which of the following organisms requires a medium through which male gametes move?

• A. Algae, Bryophyta and Gymnosperm
• B. Pteridophyta, and Angiosperm
• C. Bryophytea and Pteridophyta only
• D. Algae, Bryophyta, and Pteridophyta

Answer 1

The correct option is D Algae, Bryophyta, and Pteridophyta

• In simple plants like algae, bryophytes, and pteridophytes, water serve as the medium through which gamete transfer takes place.
• A large number of male gametes fail to reach the female gametes.
• Thus, to compensate for the loss of male gametes during transport, organisms produce male gametes several thousand times the number of female gametes produced.
