Multiple choice

What is the term for the process by which plants remove pollutants from the environment?

  1. Phytoremediation

  2. Bioremediation

  3. Phytodegradation

  4. Rhizoremediation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Phytoremediation is the process by which plants remove pollutants from the environment. Plants can absorb pollutants through their roots, leaves, and stems, and then break them down into harmless substances.

Multiple choice

What is the term for the process by which plants absorb and accumulate pollutants from the soil?

  1. Phytoremediation

  2. Bioremediation

  3. Phytodegradation

  4. Rhizoremediation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rhizoremediation is the process by which plants absorb and accumulate pollutants from the soil. Plants release exudates from their roots that can help to break down pollutants and make them more available for uptake by the plant.
