Question

Describe one way how plants respond to stimuli.

Answer 1

Stimuli:

1. Some of the common factors that affect plant growth include light, gravity, water, and touch.
2. Plant tropisms vary from other stimulus-generated movements, such as nastic motions, in that the reaction direction is determined by the stimulus.

Ways how plants respond to stimuli:

1. Because plants require sunshine to thrive, they will tilt or migrate towards the source of light.
2. Phototropism is the name given to this type of movement.
3. Negative phototropism occurs when a plant travels away from a light source.
4. Positive phototropism occurs when plants grow toward the source of light.
5. Thigmotropism is another type of plant movement in which movement happens in reaction to physical touch or stimuli.
6. When handled, the touch-me-not plant exhibits thigmotropism.
