True.

Phyllotactic ratios, which describe the arrangement of leaves, seeds, or petals in plants, often follow Fibonacci sequences. The number of petals, for instance, or the pattern in which leaves spiral on a stem, tends to correspond to Fibonacci numbers, such as 1, 2, 3, 5, 8, 13, etc.

The Fibonacci sequence is closely tied to the golden ratio, which has been widely used in art and architecture to create visually pleasing proportions.

2. What is the golden ratio, and how does it relate to Fibonacci numbers?
3. Can you name famous artists who have used the Fibonacci sequence in their works?
4. How is the Fibonacci sequence applied in modern design or architecture?

Tip: The golden ratio is often considered the "divine proportion" and has been used since ancient Greek architecture.
