2.79 Plants and Stimuli

Understand that plants respond to stimuli.

Stimuli -> Receptor -> Response

Changes in the environment leads to the plant receptors detecting stimuli which is then converted into a response, usually in the form of growth. This is called a tropism. tropism involving light is called phototropism while gravity related tropism is called geotropism. connections between the receptors and the response is the plant hormones such as auxin.
