All land plants have ________ life cycle(s).

Question

Quizplus · Accepted Answer

All land plants have an alternation of generations life cycle, where they alternate between a haploid gametophyte stage and a diploid sporophyte stage. This is a unique characteristic of land plants compared to algae, which typically have a haplontic life cycle. While some land plants may also briefly exhibit a haplontic or diplontic stage, these are not the dominant life cycle and occur only in specific circumstances. Therefore, the best choice is B, an alternation of generations.
