Detailed explanation-1: -In the nervous system, internal and external stimuli can elicit two different categories of responses: an excitatory response, normally in the form of an action potential, and an inhibitory response.
Detailed explanation-2: -Understand that signalling molecules induce cellular changes and responses in cells. Be able to transfer and apply their knowledge of this stimulus response model in terms of signal transduction as a three-step process involving reception, transduction and cellular response.
Detailed explanation-3: -Mimosa pudica is a sensitive plant. When the leaves of the plant are touched, it immediately shrinks and folds the leaves. In this type of movement, no growth is involved. Here, the leaves move in response to the touch stimulus.
