Question

Which of the following movements is not a directional movement?

• A. The bending of the shoot of a plant in response to light
• B. The closing up of leaves of a sensitive plant on being touched with an object
• C. The climbing up of a plant on an object by using tendrils
• D. The movement of the root of a plant towards a source of water

Answer 1

The correct option is B The closing up of leaves of a sensitive plant on being touched with an object

The closing of leaves of a sensitive plant on touching with an object doesn’t follow a proper direction for getting closed. While, bending of shoot of plant is always away from sunlight, climbing of a plant is always in the direction the mother plant has grown up, and movement of root is always towards the source of water.
