Plants not only remember when you touch them, but
they can also make risky decisions that are as sophisticated
as those made by humans, all without brains or complex
nervous systems.
Researchers showed that when faced with the choice
between a pot containing constant levels of nutrients or one
with unpredictable levels, a plant will pick the mystery pot
when conditions are sufficiently poor.
In a set of experiments, Dr. Shemesh, from TelHai
College in Israel, and Alex Kacelnik, from Oxford University,
grew pea plants and split their roots between two pots. Both
pots had the same amount of nutrients on average, but in
one, the levels were constant; in the other, they varied over
time. Then the researchers switched the conditions so that
the average nutrients in both pots would be equally high or
low, and asked: Which pot would a plant prefer?
When nutrient levels were low, the plants laid more
roots in the unpredictable pot. But when nutrients were
abundant, they chose the one that always had the same
amount.
