The process of preparing thin slices of wood for examination under a microscope.
Xylotomy is essential for studying the cellular structure of trees.
Xylotomy is formed from "xylo-" (from Greek "xylon", meaning wood) and "-tomy" (from Greek "tomia", meaning cutting). The word refers to the process of cutting or preparing wood specimens for study.
Think of 'wood' ('xylo-') being 'cut' ('-tomy') — that's what xylotomy means.
