Difference Between Stimulus And Response In Plants

Difference between stimulus and response events.

Difference between stimulus and response in plants. Consider the alarm at 5 o clock time equaling 5 is stimulus event and alarm ringing is response event. In plants stimulus response is done with the help of a chemical substance called as plant hormones or phyto hormones. A change in the internal or external environment is called a stimulus and is detected by a receptor.

Response a reaction to a specific stimulus. A stimulus can be internal or external. Furthermore the stimulus is a detectable change in the organism s internal or external environment while a response is specific to a stimulus.

Stimulus is the first event that takes place and the response is the result. Stimulus response stimulus something that can elicit or evoke a response in a cell a tissue or an organism. A stimulus could be of any magnitude but the response could never go beyond the highest capability of an organism.

Slow thigmotropsim is regulated by auxin which redistributes in the elongating stem in response to the touch ultimately resulting in differential cell elongation much like the role. In animals stimulus response is controlled by brain and spinal cord. Switching off the induction at temperature exceeding 100 degree.

Plants do not have brain and spinal cord. Stimulus determines the response but it never happens the other way around. Slow thigmotropism describes a plant response to a touch stimulus that affects direction of growth such as vines that wrap around or grow along structures.

2 a stimulus can cause a change in the physical and behavioral patterns of an organism while a response is how this change is manifested in the organism. The main difference between stimulus and response is that a stimulus is an event or condition which initiates a response whereas response is the organism s reaction to a stimulus. In animals stimulus response is done with the help of electrical impulses generated by the nervous system as well as the hormones secreted by the endocrine glands.
