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.
