Question: 1 / 400

What does the term "chlorosis" refer to in plants?

Yellowing of the leaves

Chlorosis refers specifically to the yellowing of plant leaves, which often indicates a deficiency in essential nutrients such as nitrogen, iron, or magnesium. This phenomenon occurs when chlorophyll production is impaired, leading to a reduction in the green pigmentation of the leaves. The yellowing primarily signifies that the plant is experiencing stress due to nutrient deficiencies, environmental factors, or diseases that affect its ability to photosynthesize effectively. Understanding this term is crucial for diagnosing plant health issues and implementing appropriate interventions to restore the plant's vigor.
