The hidden internal clocks that govern the rhythm of the natural world

How plants tell time - Dasha Savage · 4:20 · Video: TED-Ed · Watch at the source

In short: From the morning glory's dawn bloom to the waterlily's afternoon close, plants follow a precise schedule. This video explores the biological mechanisms behind these predictable patterns.

Dasha Savage investigates the circadian rhythms that serve as internal timekeepers for both plants and animals. The animation illustrates how specific species use these rhythms to coordinate life events, such as morning glories unfurling petals at dawn, white waterlilies closing in the late afternoon, and moon flowers blooming only under the night sky.
