Transpiration and Translocation GCSE

What process do plants use to make their own sugars?

• Photosynthesis

• Respiration

• Transpiration

• Translocation

What is the main function of phloem cells in plants?

• Transporting water

• Transporting mineral ions

• Supporting plant structure

• Transporting sugars

What enables the movement of cell sap between phloem cells?

• Chlorophyll

• Root pressure

• Lignin

What material strengthens xylem tubes?

• Cellulose

• Lignin

• Pectin

• Starch

What drives the movement of water through a plant?

• Root pressure

• Photosynthesis

• Capillary action

• Evaporation of water from the leaves

What is the term used to describe the evaporation of water from the leaves?

• Evapotranspiration

• Translocation

• Transpiration

• Condensation

Which factor does NOT influence the rate of transpiration?

• Airflow

• Light intensity

• Soil type

• Temperature

How does high humidity affect the rate of transpiration?

• Decreases it

• Varies depending on temperature

• Increases it

• Has no effect

What happens to the rate of transpiration at night?

• It increases

• It decreases

• It remains constant

• It stops completely

What can sugars transported by phloem be used for in the plant?

• For photosynthesis

• For energy or storage

• Only for storage

• Only for energy
