The information of touch is transmitted in the mimosa plant. Plants use electrochemical means to transmit this information from one cell to another. The leaves of the plants bend down. This is due to the reduced osmotic pressure in the base cells. When the time of stimulation is over, the leaves return to their normal state. Movement of leg : Information operates in the form of electrochemical signals. By reaching the muscles, they are converted into signals, due to which there is movement in the foot. This movement is due to the contraction and expansion of muscles which are controlled by the brain. Leg muscles are connected with nerves.

What is the difference between the movement in the mimosa plant and the mode of movement in our leg?

Question:

What is the difference between the movement in the mimosa plant and the mode of movement in our leg?

Answer:

An involuntary response to stimuli reflects the sensitive plant's movement, whereas a voluntary and conscious reaction is the leg movement.

Movement in Plants	Movement in Legs
Classified as a nastic or tropic movement. It is an intrinsic response to external/internal movement.	The neurological system controls the leg movement.
Doesn’t require any special tissues for information transmission.	The advanced neural network helps leg mobility including the CNS (Central Nervous System) and PNS (Peripheral Nervous System).
No particular proteins involved	Leg movement is facilitated by the Actin, myosin, and other proteins that helps in contraction.
