seaweed
Seaweed, or macroalgae, encompasses thousands of multicellular marine algae species spanning red, brown, and green lineages that occupy a unique position at the boundary of plant science and marine biology. These organisms are of significant interest to plant scientists because they share evolutionary lineages with terrestrial plants and employ diverse photosynthetic strategies, offering insights into the origins and diversification of plant biochemistry. Beyond their ecological roles in carbon capture and oxygen production, seaweeds are studied for their unique cell wall compositions, bioactive compounds, and stress-adaptation mechanisms that inform research into plant resilience and biotechnology.

Researchers tested four seaweed species and one salt-tolerant land plant to see how well they absorb excess nutrients from polluted water, and whether using more plants produces better cleanup results. The goal was to identify the most efficient natural filters for nutrient-laden waterways.
Four seaweed species and one halophyte (salt-tolerant plant) were evaluated for their ability to remove excess nutrients from enriched water bodies.
The study used a dosage-dependent design, meaning different quantities of each plant were tested to determine optimal biomass for maximum nutrient removal.
Growth rate was measured alongside nutrient absorption, indicating the researchers assessed whether the plants could sustain themselves while performing bioremediation.
