- Plant respond to stimuli.
- Stimuli --changes in the environment; Receptor --detect the stimuli and turn them into response; Response --reaction towards the change (often take in the form of growth)
- The response taken in the form of growth is called tropism.
- There're 2 kinds of tropism we're going to discuss: Light -phototropism and gravity -geotropism.
- Receptor produce response by plant hormones (plant growth regulator). One example is auxin.
