Transport of Water in Plants Quiz

What process is responsible for the initial absorption of water by plant roots?

• Diffusion

• Transpiration

• Osmosis

• Active transport

What specialized cells in the roots increase the surface area for water absorption?

• Xylem cells

• Guard cells

• Phloem cells

• Root hair cells

Through which vessels is water transported from the roots to the leaves?

• Xylem vessels

• Phloem vessels

• Stomata

• Guard cells

What is the process called when water is lost from the leaves as vapor?

• Transpiration

• Photosynthesis

• Respiration

• Condensation

Which factor does NOT affect the rate of transpiration?

• Light intensity

• Soil type

• Wind speed

• Temperature

What happens to the rate of transpiration as light intensity increases?

• It decreases

• It remains constant

• It increases

• It fluctuates

How does temperature affect the rate of transpiration?

• Higher temperature increases transpiration

• Higher temperature decreases transpiration

• Lower temperature increases transpiration

• Temperature has no effect

What is the effect of increased wind speed on transpiration?

• No effect

• Stops transpiration

• Decreases transpiration

• Increases transpiration

How does high humidity affect the rate of transpiration?

• Stops transpiration

• No effect

• Decreases transpiration

• Increases transpiration

What is a potometer used to measure?

• Rate of photosynthesis

• Soil moisture content

• Rate of transpiration

• Leaf surface area
