Final answer:
Fucus, a multicellular brown algae, has a life cycle that resembles that of higher animals in several ways.
Step-by-step explanation:
Fucus, a multicellular brown algae, has a life cycle that resembles that of higher animals in several ways. First, both Fucus and higher animals are diploid, meaning most of their cells have two sets of chromosomes. In addition, both Fucus and higher animals produce haploid gametes for sexual reproduction. Finally, syngamy, the fertilization process, occurs externally in both Fucus and higher animals.
