Your plants are alive. And the way you store them once you bring them
home from the grocery store could determine how many nutrients you’re
getting from them, a new study found.
A study published in Current
Biology showed that even after a plant has been harvested, its cells
are still active, and it’s still sensitive to light. In an earlier
study, the same group discovered that plants use this ability to sense
light to prepare themselves for daytime insect attacks, judged using
their circadian clocks. They pump themselves full of hormones, which
causes an accumulation of chemical compounds called glucosinolates that
repels the insects.
