Kingdom of Plants 3D 2012. Sir David Attenborough explores the world of plants at the Royal Botanic Gardens in Kew. The gardens contain approximately ninety percent of all known plant species. Attenborough traces plant history from their first appearance on land to the present day. Specialized 3D cameras capture growth, movement, and interaction. The footage reveals plants are aggressive and agile, not passive organisms. They compete for resources. They communicate with each other. They adapt to changing conditions. The series documents pollination, predation, and symbiosis. Attenborough explains the vital role plants play in nature. The gardens serve as a living laboratory for understanding the plant kingdom.
