“With his makeshift centrifuge, Knight had applied a force on the seedlings that mimicked gravitation and demonstrated that the roots always grew in the direction of this centrifugal force-while the shoots grew in the opposite direction. Knight's work provided the… — Daniel Chamovitz Copy Share Image
“In his phototropism experiment, he showed that the tip of a shoot sees the light and transfers this information to its midsection to tell… — Daniel Chamovitz Copy Share Image
“A recent (and provocative) study in Science showed that men who simply sniffed negative-emotion-related odorless tears obtained from women showed reduced levels of testosterone… — Daniel Chamovitz Copy Share Image
“Plants are not cognizant. When we cut a leaf, we assume that the plant is suffering. But that's our own anthropomorphism about what's going… — Daniel Chamovitz Copy Share Image
“Darwin found that all plants move in a recurring spiral oscillation, which he termed "circumnutation" (Latin for "circle" or "sway"). This spiral pattern varies… — Daniel Chamovitz Copy Share Image
“They compared the compounds emitted by leaves following bacterial infection with those emitted following an insect feeding. Both treatments resulted in the expression of… — Daniel Chamovitz Copy Share Image
“A plant can be pulled in many directions at once. Sunlight hitting a plant at an angle caises it to bend toward the rays,… — Daniel Chamovitz Copy Share Image
“Flying halfway around the world puts our circadian clock out of sync with the day-night signals, a phenomenon we call jet lag. The circadian… — Daniel Chamovitz Copy Share Image

“Plants are acutely aware of the world around them. They are aware of their visual environment; they differentiate between red, blue, far red, and… — Daniel Chamovitz Copy Share Image
“While the mechanisms involved in electrochemical signaling are complex, the basic principles are simple. Just as a battery maintains its charge by housing different… — Daniel Chamovitz Copy Share Image
“These weightless plants were placed on a large rotating centrifuge that mimicked gravitation, much as Knight's waterwheel had years and years earlier. The plants… — Daniel Chamovitz Copy Share Image
“My grandmother didn’t study plant biology or agriculture. She didn’t even finish high school. But she knew that she could get a hard avocado… — Daniel Chamovitz Copy Share Image
