In the tree a knot is either the base of a side branch or a dormant bud. A knot (when the base of a side branch) is conical in shape (hence the roughly circular cross-section) with the inner tip at the point in stem diameter at which the plant's vascular cambium was located when the branch formed as a bud.

QSN1 Other than the base of a side branch, what tree feature causes a knot? ANS1 a dormant bud QSN2 What shape is the knot formed by a side branch's base? ANS2 conical QSN3 What measurement of a stem determines a knot's inner tip placement? ANS3 diameter QSN4 Because a knot's shape is conical, what shape does a cross-section of it have? ANS4 circular
