Motile male gametes are present in which one of the following sets?

• A. Riccia, Dryopteris and Cycas
• B. Anthoceros, Funaria and Spirogyra
• C. Zygnema, Saprolegnia and Hydrilla
• D. Fucus, Marsilea and Calotropis

Answer 1

The correct option is A Riccia, Dryopteris and Cycas

Flagellated male gametes are present in Riccia,Dryopteris and Cycas. The male gametes of bryophytes are biflagellate, and those of pteridophytes are multiflagellate, except Selaginella having biflagellate gametes. The male gametes of gymnosperms are non motile except those of Cycas having multiciliate gametes. Hence option A is correct.
