Extensive Definition
Irritability is an excessive response to stimuli.
Irritability takes many forms, from the contraction of a unicellular
organism when touched, to complex reactions involving all the
senses of higher animals.
In plants, response is
usually different from that seen in animals, but is nonetheless
present. The term irritability is used for both the physiological reaction to

environmental, situational, sociological, and emotional stimuli.
