Question

Plants do not have any nervous system but yet, if we touch a
sensitive plant, some observable changes take place in its leaves.
Explain how could this plant respond to the external stimuli and
how it is communicated.
​

Answer 1

Answer:

Plants do not have a nervous system like animals but are known to respond to a number of external stimuli with the help of receptors and hormones. The receptors help the plants to sense the external stimulus and act accordingly. As a result of these stimuli, various growth hormones are produced which result in the movement or directed growth of the plant. A similar response is observed when the leaves of Touch-me-not plants

are touched. They show seismonastic movement due to the presence of receptors for touch stimulus.....
