What does the term "chlorosis" refer to in plants affected by pesticides?

  1. Wilting of plant stems

  2. Yellowing of green portions of a plant

  3. Excess growth of roots

  4. Drying of leaves

The correct answer is: Yellowing of green portions of a plant

Chlorosis refers to the yellowing of the green portions of a plant, particularly the leaves. This discoloration is a common symptom of plants affected by pesticides, indicating a disruption in the plant's ability to produce chlorophyll. Wilting of plant stems, excess growth of roots, and drying of leaves are not specifically associated with the term "chlorosis" in relation to pesticide effects on plants.
