3.3 Plant & Animal Responses

2. The growth of a plant in response to moisture, typically where roots grow towards a water source.
3. The large-scale movement of a species from one location to another, often in response to seasonal changes or breeding needs.
6. The growth of a plant in response to light
8. A plant hormone that regulates growth by promoting cell elongation and directing responses to environmental stimuli such as light and gravity.
12. The movement of an organism towards or away from light.
13. The movement of an organism towards or away from a source of heat.
14. A change in an organism's environment to which it can respond.
15. A form of kinesis where the speed of movement is proportional to the intensity of the stimulus.

1. The growth of a plant in response to gravity, where roots grow downwards and shoots grow upwards.
4. The growth or movement of a plant in response to an environmental stimulus
5. A directed movement towards or away from a stimulus.
7. A directional growth response of a plant to touch or physical contact with an object.
9. The movement of an organism in response to a chemical stimulus.
10. A non-directional movement in response to a stimulus, where the speed or frequency of movement changes.
11. A structure that detects stimuli and sends a signal to another part(s) of the organism.
