(d) In brown algae, sexual reproduction is isogamous (in Ectocarpales), anisogamous (in Cutleriales) and oogamous (in Fucus, Laminaria, Dictyota, etc). In most of the brown algae, the gametes are pyriform form and flagellated. Fertilisation is external, i.e., the gametes fuse outside the gametangia in water |
