OCR Movement of water through the root

How does water enter root hair cells?

• By osmosis
• By active transport
• By diffusion
• By transpiration

What is the purpose of root hair cells in water absorption

• To provide structural support to the root
• To pump mineral into the xylem tissue
• To create a water potential gradient
• To provide a large surface area for water absorption

How are minerals absorbed through root hair cells

• By osmosis
• By active transport
• By diffusion
• By transpiration

What are the two pathways for water movement across the cortex of the root?

• Symplast and Osmotic
• Diffusion and active transport
• Sympast and Apoplast
• Osmosis and transpiration

What is the role of the Casparian strip in the endodermis?

• To prevent the movement of water
• To facilitate the movement of water
• To provide strucutral support
• To store minerals

What happens when water encounters the Casparian strip in the endodermis

• It penetrates the strip easily
• It continues to move through the Apoplast pathway
• It enters the symplast pathway
• It exits the roots through transpiration

What is the entry point of water into the xylem vessel?

• Root hair cells
• Endodermis
• Casparian strip
• Pit in xylem vessel

Which pathway allows water to move through the water-filled spaces between cellulose molecules in the cell walls?

• Symplast pathway
• Osmotic pathway
• Apoplast pathway
• Transpiration pathway

What is the function of plasmodesmata in the symplast pathway?

• To facilitate osmosis
• To provide structural support
• To connect the cytoplasm of neighbouring cells
• To pump minerals into the xylem vessel

What is the driving force for water movement in the root?

• Active transport
• Osmosis
• Transpiration
• Water potential gradient
