What is an area of infected (diseased, dying, or dead) tissues on a plant part?

• A. Lesion
• B. Wilt
• C. Necrosis
• D. Chlorosis

Answer: (A)

A lesion is a localized patch of plant tissue that has been damaged or diseased. It appears as a distinct spot or area on leaves, stems, or other parts where infection, decay, or injury has altered the tissue, making it look different from healthy tissue. Wilt describes a drooping condition of the plant, not a specific patch. Necrosis means tissue has died, but it’s the process/state of death rather than the clearly defined diseased area on the plant part. Chlorosis is yellowing from loss of chlorophyll, not a defined diseased patch. So the area of infected or damaged tissue on a plant part is best described as a lesion.
