A plant's abnormal growth built by a parasite ordering room service through its tissue.
means A gall — an abnormal swelling or outgrowth on a plant, produced by the plant's own tissue in response to insects, mites, fungi, or other organisms living in or on it.
from From the Greek 'kēkis' (κηκίς), meaning a gall-nut or oak-apple — the growth that forms on oak trees where gall wasps lay their eggs. The term passed into modern scientific Latin as 'cecidium,' adopted by botanists to name these parasite-induced plant growths generally, and it now anchors the whole field of 'cecidology,' the study of galls.
