Redwoods typically provoke wonder at the macro scale. They are, after all, the largest and tallest trees in the world. But in this visualisation from the California Academy of Sciences in San Francisco, viewers are invited on a remarkable tour through several levels of organisation in a redwood tree leaf, from scales measured in centimetres down to nanometres. Starting at the stomata, where carbon dioxide enters the plant, before finally landing at the thylakoid membrane, where light-based photosynthetic reactions occur, the animation reveals just some of the extraordinarily complex systems underpinning what we might easily overlook as a mere leaf. For more details and data, watch the annotated version of the video here.
