How is the movement of leaves of the sensitive plant different from the movement of a shoot towards light?
Thigmotropism
The movement of the sensitive plant's leaves is touch-sensitive and independent of growth, which is known as thigmotropism.
Phototropism
The growth-related tendency of the shoot toward light is known as phototropism.
Thigmotropism | Phototropism |
1.The movement of the sensitive plant's leaves is a nastic movement known as thigmotropism. | 1.Phototropism is a tropical movement that causes a shoot to gravitate towards light. |
2. Plants typically exhibit non-directional nastic motions with no specific route. | 2.Tropical motions are unidirectional, depending on where the stimulus originates from. |
3.Nastic motions are quick. | 3. Tropical motion is extremely slow. |
4. These motions are conveyed by a plant's flat parts (such as leaves and petals). | 4. All sections of a plant express these motions, as in the movement of a shoot toward the light rather than gravity. |
