Comparative analysis of plant family representation in phytoremediation candidate species. The line graph shows species abundance patterns across four major plant families, with Asteraceae (Daisy Family), Brassicaceae (Mustard Family), Fabaceae (Legume Family), and Poaceae (Grass Family) demonstrating varying ecological niches. Root system illustrations emphasize the complementary soil interaction strategies, from taproot penetration to fibrous root networks suitable for contaminated site restoration.
