Xylem and Phloem Transport Quiz

What is the main function of xylem in plants?

• Converting sunlight into energy

• Producing flowers and fruits

• Anchoring the plant to the ground

• Transporting water and dissolved mineral nutrients

The xylem is made up of...

• Phloem cells

• Guard cells

• Root hairs

• Dead cells

What is the process called by which water moves through the xylem from roots to leaves?

• Transpiration

• Capillarity

• Photosynthesis

• Respiration

What is the main function of phloem in plants?

• Producing oxygen

• Regulating water intake

• Supporting the plant structure

• Transporting glucose, fatty acids and amino acids

Which type of cells are responsible for transporting sugars and other organic compounds in the phloem?

• Living cells called sieve tube elements

• Guard cells

• Red blood cells

• Neurons

What is the process called by which sugars move through the phloem from leaves to other parts of the plant?

• Respiration
