Why do some plants grow in spirals?

Spiral growth patterns in plants, such as those seen in sunflowers and pinecones, are examples of phyllotaxis, a strategy for optimising space and light capture. Spirals often follow the Fibonacci sequence, which ensures efficient packing of seeds, leaves, or flowers. This arrangement minimises overlap, allowing each leaf or seed to receive adequate sunlight or nutrients. Spiral patterns are not only functional but also create visually striking structures in nature.
