The Anatomy of Trees

Trees have a complex structure that varies depending on the species. Here are some terms related to their anatomy:

2. Branches

Branches are extensions of the trunk that grow in different directions. They support the leaves and allow the tree to reach for sunlight and water.

3. Leaves

Leaves are the primary organs of photosynthesis in trees. They absorb sunlight and carbon dioxide to produce oxygen and glucose.

Roots are the underground organs that anchor the tree to the soil and absorb water and nutrients. They can grow to be much larger than the visible parts of the tree.

Understanding the anatomy of trees is essential for proper tree care and management. Pruning, fertilization, and pest control are all influenced by the structure of the tree.
