How can a floating pond plant such as duckweed survive without having its roots in soil?

Duckweed can survive without roots in soil because it absorbs nutrients and water directly from the surrounding water through its leaves. This adaptation allows it to thrive in aquatic environments where soil is absent. Additionally, duckweed can photosynthesize efficiently, using sunlight to produce energy. Its buoyant nature enables it to float and access light while simultaneously facilitating nutrient uptake.
