Are Plants Using Quantum Entanglement In Photosynthesis?

Michael Moyer writes in Scientific American:
As nature’s own solar cells, plants convert sunlight into energy via photosynthesis. New details are emerging about how the process is able to exploit the strange behavior of quantum systems, which could lead to entirely novel approaches to capturing usable light from the sun. All photosynthetic organisms use protein-based “antennas” in their cells to capture incoming light, convert it to energy and direct that energy to reaction centers — critical trigger molecules that release electrons and get the chemical conversion rolling. These antennas must strike a difficult balance: they must be broad enough to absorb as much sunlight as possible yet not grow so large that they impair their own ability to shuttle the energy on to the reaction centers. EntangledThis is where quantum mechanics becomes useful. Quantum systems can exist in a superposition, or mixture, of many different states at once. What’s more, these states can interfere with one another — adding constructively at some points, subtracting at others. If the energy going into the antennas could be broken into an elaborate superposition and made to interfere constructively with itself, it could be transported to the reaction center with nearly 100 percent efficiency.

Green Sea Slug Is Half Animal, Half Plant

sea slugFrom PRESSTV:

Scientists have identified a sea slug Elysia chlorotica able to synthesize chlorophyll like a plant as the first animal with herbal characteristics.

The animal enjoys genes that allow it to be the first animal identified showing plant features. Those genes help the sea slug make chlorophyll; compared to such an ability, its green color is no longer seen as strange.

Scientists from the University of South Florida have identified this green sea slug as the first animal known to be capable of the feat.

“This could be a fusion of a plant and an animal – that’s just cool,” said invertebrate zoologist John Sardis of the Citadel in Charleston…
