Life cycle of Ectocarpus and Fucus respectively are:
- ADiplontic, Haplodiplontic
- BHaplodiplontic, Diplontic
- CHaplodiplontic, Haplontic
- DHaplontic, Diplontic
Solution & Step-by-step Explanation
Ectocarpus (a brown alga) exhibits a haplodiplontic life cycle where both haploid and diploid phases are multicellular. Fucus (another brown alga) is an exception among most algae as it exhibits a diplontic life cycle, similar to seed-bearing plants.
