The movement of plants in response to touch stimulus is called:
Correct answer: D. Thigmotropism
- A. Hydrotropism
- B. Chemotropism
- C. Geotropism
- D. Thigmotropism
- E. Phototropism
Explanation
Thigmotropism is a directional growth movement that occurs as a mechanosensory response to a touch stimulus. It is typically found in twining plants and tendrils, however, plant biologists have also found thigmotropic responses in flowering plants and fungi. Phototropism is movement in response to light, geotropism is movement due to gravitational forces, chemotropism is movement in response to chemicals.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
