Question

Quizplus · Accepted Answer

Hyperaccumulators are plants that can take up extremely high amounts of certain metals without being harmed. They are able to survive on metal-contaminated soil by growing without taking in too much of the metal in question, making them useful for phytoremediation efforts. They are not necessarily sensitive to the toxic effects of heavy metals and do not necessarily develop dense root mats above polluted soil.
