Trees grow toward the sun.

Sometimes a proud tree is bent and broken by powerful natural forces. The broken parts heal, but reaching for the sun again takes something special...a thing called Reaction Wood.

Trees grow toward the sun. But how do they straighten up when bent? Reaction wood is formed. This wood has an unusual amount of Lignin. In broad-leaf trees this abundance of lignin causes the growth cells on the top part of the limb to grow shorter. Over a period of time the tree is forced to grow upward again. Then the tree starts growing vertically again, the cells go back to normal. In conifers lignin causes the bottom growth cells to grow longer, which has the same effect. This is remarkable. How does the tree know to change?

God’s creative power and concern is awesome!
