Answer 1

This process is called phytoextraction.

The plants store the contaminants in their tissue.

The publication:

Shows that "the common aquatic plant duckweed sequesters many persistent organic compounds in its plant tissue, thus removing these contaminants from natural waters and engineered wetlands."

"Duckweed does not degrade the compound, so the plant fixes it inside cell walls and tissue, eliminating the compounds' toxic effect on the plant."
