The appearance of knots in sawn wood and veneer is caused by grain deviation to accommodate the wood found inside the branches of trees. As the tree grows taller, the crown shades older and lower branches so they tend to die off and are subsumed by the increasing girth of the trunk.

What problems do knots in wood cause?
Wood Knots in Building Wood knots weaken wood strength. In fact, knots materially affect cracking (known is the US as “checks”; known in the UK as “shakes”), warping, and the ease of working the lumber. They are defects that lower the lumber's value for structural purposes where strength is critical.
How do you stabilize knots in wood?
Thankfully, cyanoacrylate (CA) glue saves the day. Thin CA glue is about the consistency of water, and it's the perfect choice for saving the character in this piece. Dribble the glue around the edge of the knot, allowing it to seep in and run down alongside it.
Should you fill knots in wood?

What does a knot mean in a tree?
Knots in trees occur where a branch has been surrounded by continued growth of the bole. When the bole is sawn into lumber, or peeled to make veneer, the branch sections included in the lumber or veneer show up as knots. Whether a knot is red or black was determined back when the tree was growing.
What is a knot on a tree called?
Tree knots are also known as “burls”. Burls form on the outside of trees as a reaction to stress.
Why do trees get knots?
Knots in wood are formed when branches are broken off or cut, and the exposed wood is left behind. As the tree continues to grow, the trunk expands and overtakes the branches, and knots form around the base of the branches. Knots can also be formed by injuries to the tree or by fungal infections.

Do not let the epoxy touch your skin.
What is a knot of a tree?
