What is tropism?
A plant's response to a stimulus
A plant reproducing
An animal's response to a stimulus
A prokaryote's response to a stimulus
Which of these are types of tropism? Select all that apply:
Hydrotropism
Synthetropism

Gravitropism
What is gravitropism/geotropism?
The movement of a plant in response to gravity
The movement of a plant in response to earthquakes
The movement of bacteria in response to changes in temperature
The movement of plants towards water
What is hydrotropism?
The movement of plants towards water
The movement of plants away from water
The rate of growth of a plant in response to temperature changes in water
A plant's response to gravity and touch
What makes a tropism positive or negative?
Positive = movement towards stimulus, Negative = movement away from stimulus
Negative = movement towards stimulus, Positive = movement away from stimulus
Who cares? It doesn't matter whether it is positive or negative
Positive = when a plant is happy, Negative = when a plant is sad
What is thigmotropism?
The movement of plants in response to touch
The movement of plants toward the sun

The movement of plants in response to gravity
What is phototropism?
The movement of plants towards light
The movement of plants away from light
The movement of plants in response to infrared light
The movement of plants towards water
