What condition is described by the yellowing of leaves?

The yellowing of leaves is known as chlorosis, a condition that occurs when leaves do not produce enough chlorophyll, the pigment responsible for the green color in plants. This deficiency can arise due to various reasons, such as nutrient deficiencies, poor soil conditions, water stress, or diseases. In plants exhibiting chlorosis, the yellowing is often most pronounced between the leaf veins, while the veins themselves may remain green. This condition can significantly impact a plant's ability to photosynthesize effectively, leading to reduced growth and vigor. Understanding chlorosis is essential for identifying plant health issues and implementing appropriate corrective measures.
