how does the action due to nervous tissue in animals is different from response to stimulus in plants?
Answers
Movement in a sensitive plant
(i) It occurs in response to an external stimulus like touch and shock.
(ii) Plant cells change shape by changing the amount of water.
(iii) No nerves are involved.
(iv) There is no specialized tissue in plants for conduction of information.
(v) Plant cells do not have specialized proteins.
Movement in our legs
(i) It occurs in response to our requirements and is a voluntary action.
(ii) Movement in our legs is voluntary action which is controlled by cerebellum part of hind brain.
(iii) Nerves carry the message for movement of legs.
(iv) There is specialized nervous tissue in animals for conduction of information and muscle cells to help in movement.
(v) Animal cells have specialized protein which help muscles to contract or relax.

The action due to nervous tissue in animals is different from response to stimulus in plants
Explanation:
- The nervous tissues in animals act by responding to external and internal stimuli through electrical signals conducted by chemicals called neurotransmitters, which triggers action potentials which initiate the responses to the stimuli.
- Plants lack a nervous system with tissues like in animals but they have perception system which helps it to understand, respond and adapt to the environment or surrounding with the help of its own physiology and morphology.
- Plants respond to various external stimuli like light, heat, moisture, temperature etc and deliver electrical signal pathway with the help of neurochemicals which aids in delivering the action potentials required for the response.
