User: How does a pine cone work?
Assistant: A pine cone consists of scales which protect seeds. The scales can open and close depending on conditions. The scales will open temporarily to receive pollen, then close again until the seeds mature. Once mature, the scales will open and close depending on their moisture content. Once the seeds are mature, the scales can open again to allow seeds to escape. When dry, the cones open allowing the small windborne seeds to disperse as widely as possible. This cycle of opening and closing continues until the seeds are dispersed.
