Did You Know?
1. Carbon Storage: Trees are composed of approximately 50% carbon, making them natural carbon sinks. They absorb carbon dioxide from the atmosphere during photosynthesis and store it in their trunks, branches, leaves, and roots.
2. Cellulose Superstructure: The main structural component of trees is cellulose, a complex carbohydrate. Cellulose molecules are arranged in a way that allows trees to be strong and rigid, enabling them to maintain their shape and withstand external forces.
3. Lignin For Support: To provide additional strength and rigidity, trees contain a substance called lignin. This polymer acts like a natural glue, binding cellulose fibers together and giving trees the structural integrity needed to stand tall and support their weight.
4. Ring Count: The number of rings found in a tree trunk can be used to determine its approximate age. Each ring represents a year of growth, with thicker rings indicating years of favorable conditions, and thinner rings indicating less favorable conditions, such as drought or colder weather.
5. Deciduous vs. Evergreen: The composition of trees can also differ depending on their classification as deciduous or evergreen. Deciduous trees, such as maple or oak, lose their leaves seasonally and their composition shifts between seasons. Evergreen trees, like pine or spruce, retain their foliage year-round, maintaining a more consistent composition throughout the seasons.
