Tree branches are the extensions of a tree's trunk that grow outward and upward. They play a crucial role in supporting the tree's leaves, flowers, and fruits. Branches vary in size and shape, depending on the type of tree, and they help the tree capture sunlight for photosynthesis, which is essential for its growth. Branches also provide habitat and food for various animals, including birds and insects. The structure of branches can influence how a tree interacts with its environment, affecting factors like wind resistance and light exposure. Overall, branches are vital for a tree's health and ecosystem.
