Frequently Asked Questions
No, it is a highly specialized term used almost exclusively in academic botany and plant physiology.
No. The term 'nasty' is specific to plant movements. Animal responses to chemicals have different names (e.g., chemotaxis).
The opening and closing of certain flowers in response to ethylene gas or other atmospheric chemicals is a documented chemonastic response.
Because 'nasty' describes a reversible, non-directional movement of an organ, while 'tropism' describes directional growth of the entire plant toward or away from a stimulus.
A movement or response of a plant part, such as a leaf or petal, induced by a non-directional chemical stimulus.
