Difference between response to stimulus in animals and plants
Similarities and differences between response to stimulus in animals and plants are as follows:
Movement due to growth in plants
Look carefully at the image.
- The stem and leaf tendrils are sensitive to touch .
- When they come in contact with the support, a hormone called auxins is synthesized and it diffuses to the other side of the plants.
- This makes the rate of growth of tendrils less as compared to the other parts of the plants .
- The tendrils cling on to a support (eg. bamboo stick) and grows on by circling around the stem for support.
This is a growth that is directional (up the support) and so it appears as movement.
