• Phototropism

• Germination

• Turgor pressure

• Thigmotropism

• High turgor pressure

• Low turgor pressure

• Gravity

• Sunlight

If a plant experiences a phototropism, then it will do what?

• Grow toward or away from light. 
• Grow away from light. 
• Grow toward light.
• Grow in response to gravity. 

If a plant experiences a gravitropism, then it will do what?

• Grow toward or away from light. 
• Grow away from light. 
• Grow toward light.
• Grow in response to gravity. 

What does it mean if a plant has a POSITIVE phototropism?

• That the plant grows toward light.
• That the plant grows away from light.
• That the plant grows toward gravity.
• That the plant grows away from gravity. 

What does it mean if a plant has a POSITIVE gravitropism?

• That the plant grows toward light.
• That the plant grows away from light.
• That the plant grows toward gravity.
• That the plant grows away from gravity.
