Quizplus · Accepted Answer

Knots are parts of a branch or limb that have become enclosed within the tree as it grows. They represent the point at which a branch was once attached to the tree, and as the tree grows in diameter, these branches can become fully encapsulated by the growing layers of wood, leading to the formation of a knot in the lumber produced from that tree.
