Diplontic life cycle is seen in ________.

Step-by-step solution

Plants, depending on their types, show alternation of generations. In one type, the diploid sporophyte is the dominant, photosynthetic, independent phase of the plant. The gametophytic stage is represented by the single-celled to few celled haploid gametophytes. This kind of life cycle is termed as diplontic. An alga, Fucus sp., represents this pattern.
