What is transpiration?

• The process of converting sunlight into energy in plants

• The absorption of water by the roots of a plant

• The movement of nutrients within a plant

• The evaporation of water from the leaves of a plant

Which factor does not affect the rate of transpiration?

• Humidity

• Soil pH

• Temperature

• Wind

What effect does light have on transpiration?

• Decreases transpiration

• Has no effect on transpiration

• Increases transpiration

• Stops transpiration completely

What is the purpose of using a potometer in studying transpiration?

• To measure the rate of water uptake by the plant

• To measure the rate of nutrient absorption by the roots

• To measure the rate of photosynthesis in the plant

• To measure the rate of water evaporation from the leaves

Which condition would slow down transpiration?

• Bright light

• Low temperature

• High humidity

• Strong wind

What is the role of xylem tissue in transpiration?

• Regulates the opening and closing of stomata

• Converts sunlight into energy

• Transports water within the plant

• Absorbs water from the soil

How does wind affect transpiration?

• Decreases the rate of transpiration

• Stops transpiration completely

• Has no effect on transpiration

• Increases the rate of transpiration

What happens to transpiration in hot conditions?

• Decreases

• Increases

• Stops completely

• Remains the same

What is the relationship between photosynthesis and transpiration?

• Interconnected processes

• Opposite processes

• Independent processes

• Unrelated processes

How does humidity affect transpiration?

• Has no effect on transpiration

• Stops transpiration completely

• Decreases transpiration

• Increases transpiration
