Based on the picture shown (the plant growing towards the sun) predict which type of phototropism this plant will have.
Positive
Negative
This photo is demonstrating a plants response to water. Also, known as (a)
This plant was tipped on its side, it's roots continue to grow downward, and its stem up. This response to gravity is known as ______________.
phototropism
thigmotropism
gravitropism
hydrotropism
This plant is growing towards the light, this is an example of ___________.
phototropism
thigmotropism
gravitropism
hydrotropism
This plant is growing its roots towards water, this is an example of ___________.
phototropism
thigmotropism
gravitropism
hydrotropism
A plant's response to an environmental stimuli is known as a _______.
action
tropism
reply
What type of tropism is this?
Positive Geotropism
Negative Geotropism
Positive Thigmotropism
Negative Thigmotropism
Is hydrotropism negative or positive?
Positive
Negative
Neither
Both
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
Movement toward a stimulus
hydrotropism
positive tropism
dormancy
stimulus
Movement away from a stimulus
geotropism
hydrotropism
stimulus
negative tropism
The diagram shows a plant growing while lying on its side. How is the plant reacting positively and negatively to gravity?
the root are reacting negatively by growing downward while the stem and leaves are reacting positively by growing upward
the root are reacting positively by growing downward while the stem and leaves are reacting negatively by growing upward
only the roots are reacting by growing downward
only the leaves and stem are reacting by growing upward

The diagram shows a shoot growing towards light.
Which statement about the role of auxin in phototropism is correct?
Auxin will move to the dark side of the shoot and cause cells to elongate.
Auxin will move to the dark side of the shoot and prevent cells from elongating.
Auxin will move to the light side of the shoot and cause cells to elongate.
Auxin will move to the light side of the shoot and prevent cells from elongating.
