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
Electrotropism
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
A prokaryote's movement inside the bloodstream
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
Match the following stimuli with their response names:
touch
thigmotropism
gravity
gravitropism
light
phototropism
The roots have negative
phtotropism
Thigmotropism
Gravitropism
Hormones
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
A plant drops its leaves and appears to be dead.
Hibernation
Migration
Dormancy
What is a cause of plant dormancy?
Less dayling
Not enough water
Too much wind
Exercise
What can happen if certain plants don't go dormant?
damage to stems
no photosynthesis
tropisms won't work
leaves change color
Select all that are products of Photosynthesis.
Water
Carbon Dioxide
Oxygen
Sunlight (Light Energy)
Glucose (Sugar/food)
How does most of the water needed by the plant get into its leaves?
It enters through the stomata
The roots absorb it and then it travels up the stem
It's made during a chemical reaction in the leaf
The flowers capture water and deliver it to the leaves
Which organelle is responsible making food (Glucose) using sunlight?
Cell Membrane
Nucleus
Chloroplast
Mitochondria
Which of the following is the correct equation for PHOTOSYNTHESIS?

C6H12O6 is the chemical formula for this important molecule made during photosynthesis
carbon dioxide
glucose
oxygen
light energy
Cellular respiration is...
the process by which cells break down glucose into energy.
the process by which cells break light down into energy.
the process by which cells communicate with other cells.
In which way are photosynthesis and cellular respiration different?
Cellular respiration stores ATP, while photosynthesis releases ATP.
Cellular respiration produces oxygen, while photosynthesis uses oxygen.

glucose + carbon dioxide ---> ATP + oxygen + water
Which of the following is the chemical equation for cellular respiration?
C₆H₁₂O₆ + O₂ → ATP + CO₂ + H₂O
CO₂ + H₂O → ATP + C₆H₁₂O₆ + O₂
C₆H₁₂O₆ + H₂O → ATP + CO₂ + O₂
C₆H₁₂O₆ + CO₂ → ATP + H₂O + O₂

water doors
stomata
leaf eyes
transpiration holes
