Tree branches are the extensions of a tree's trunk that grow outward and upward. They support leaves, flowers, and fruits, playing a crucial role in photosynthesis, which is how trees make their food. Branches vary in size, shape, and strength, depending on the tree species and its environment. Branches also provide habitat and food for various animals, including birds and insects. They can be thick and sturdy or thin and flexible, allowing trees to adapt to different conditions. The arrangement of branches can affect how sunlight reaches the leaves, influencing the overall health of the tree.
