Why are the trunks straight and branches?

Trunks are typically straight to provide structural support and stability, allowing trees to grow tall and access sunlight more efficiently. Branches, on the other hand, grow outwards and at angles to maximize their exposure to sunlight and to create space for leaves to photosynthesize. This design also helps distribute weight and allows for better nutrient and water transport throughout the tree. Overall, the straight trunk and angled branches are adaptations that optimize growth and survival.
