How competing reproductive needs shaped the evolution of liverworts
Liverworts reproduce through a life cycle involving two distinct stages. First, sperm fertilize eggs in the presence of water, producing embryos that develop into spore-producing structures called sporophytes.
AI Summary
Liverworts reproduce through a two‑stage life cycle. Sperm must meet eggs in water, creating embryos that grow into sporophytes. The sporophytes produce spores that disperse and grow into new plants. Bryophytes—including liverworts, hornworts, and mosses—must balance water‑dependent fertilization with spore dispersal, which is favored by drier conditions. The study highlights how these contrasting reproductive demands have shaped liverwort evolution.
