A swelling of plant tissue is called

• A. Gall
• B. Wilt
• C. Mosaic
• D. Canker

Answer: (A)

Swelling of plant tissue is called a gall. This term describes a localized, tumor-like growth that forms on leaves, stems, or roots when a plant tissue responds abnormally to a stimulus such as an insect or mite feeding, egg-laying, or a pathogen that alters growth hormones. Galls are often specific to the host and the organism involved, and they create a noticeable swelling rather than a pattern or lesion. Wilt refers to loss of turgor and drooping from water stress or vascular disease, not swelling. Mosaic describes viral symptoms that produce mottled or mosaic patterns on leaves, not tissue swelling. Canker is a sunken or dead lesion on bark or stems, not a swelling.
