Question

Give one word for the following

Movements of a plant towards or away from the direction of a stimulus.

Answer 1

Tropism:

1. In response to different types of environmental stimuli like light, gravity, water, contact, chemical, etc. plants show unidirectional and irreversible movements. This phenomenon is called tropism.
2. In positive phototropism, stems bend toward the light, and in negative phototropism, roots move away from the light source.
3. In tropism, plants show their movement towards or away from the direction of a stimulus.

There are five types of tropism-

1. Phototropism: Phototropism is a phenomenon in which plants show their movements in response to light stimuli.
2. Geotropism: Geotropism is a phenomenon in which plants show their movements in response to gravity.
3. Chemotropism: Chemotropism is a phenomenon in which plants show their movements in response to a chemical stimulus.
4. Hydrotropism: Hydrotropism is a phenomenon in which plants show their movements in response to the water stimulus.
5. Thigmotropism: Thigmotropism is a phenomenon in which plants show their movement in response to contact or touch stimulus.
