Turns out living animals aren't the only ones with internal clocks. Plants also have them and they're driven by sugar! Trace explains how they work. Read More: Plants Discovered To Have Ability to Tell Time: 'Sugars In Plants Are Key To Timekeeping' "Researchers have recently discovered plants' ability to tell time. According to research published in the journal Nature, plants use sugars to tell the time of day. Like animals, plants have a circadian clock that provides a competitive advantage in the environment, influenced by Earth's rotation." Photosynthetic entrainment of the Arabidopsis thaliana circadian clock "Circadian clocks provide a competitive advantage in an environment that is heavily influenced by the rotation of the Earth, by driving daily rhythms in behaviour, physiology and metabolism in bacteria, fungi, plants and animals." How plants tell time "Gardeners often marvel at how plants of the same species tend to flower, fruit and go to seed with remarkable synchronicity, as if on cue." Plants Use Sugars to Tell the Time of Day "Plants, like animals, have a 24 hour 'body-clock' known as the circadian rhythm. This biological timer gives plants an innate ability to measure time, even when there is no light -- they don't simply respond to sunrise, for example, they know it is coming and adjust their biology accordingly."

03:00 - - A few centuries ago, the arbiter of "local noon" wasn't the mechanical clock, it was the sundial. The pseudoscientific-sounding "equation of time" is how you convert between the two -- and perhaps not the way you'd expect.

Everything from the mysterious phenomenon of "early morning" heart attacks in humans -- to how tiny nocturnal mammals evade predators -- to the blooming of plants -- is regulated by an organism's internal "biological clock." With support from the National Science Foundation, Jonathan Arnold and his team from the University of Georgia study the genetic underpinnings of these fascinating internal timekeepers using a most unlikely model system: bread mold. Arnold says the mold has plenty in common with both plant and human clocks. And the simplicity of bread mold has allowed this team to produce the first functional model of how a biological clock works. Deeper understanding this time regulator could help other scientists understand aging, artery blockages, jet lag, and why some people can work third shifts effortlessly while for others it is difficult and even dangerous.
