Water and Mineral Transport in Plants

What process transports minerals from the soil to root cells when the soil has a lower mineral concentration than the root cells?

• Diffusion

• Osmosis

• Active transport

• Passive transport

What happens to the water potential in root hair cells when there is a high concentration of minerals in the cell sap?

• It increases

• It decreases

• It remains the same

• It becomes zero

How does water move from the soil to the root hair cells?

• Active transport

• Osmosis

• Diffusion

• Transpiration

What is the direction of water movement when the water potential in the soil is higher than in the root hair cells?

• Soil to root hair cells

• Root hair cells to soil

• Cortex to root hair cells

• Xylem to soil

What happens to the water potential in root hair cells after water enters them?

• It decreases

• It increases

• It remains unchanged

• It becomes negative

What structure in the endodermis prevents water leakage from the xylem vessels?

• Plasmodesmata

• Casparian strip

• Cortex

• Epidermis

Which route is blocked by the Casparian strip in the endodermis?

• Symplastic route

• Apoplastic route

• Transmembrane route

• Vascular route

What happens to water moving via the apoplastic route when it reaches the endodermis?

• It stops moving

• It moves via the symplastic route

• It evaporates

• It leaks out of the root

Where do endodermal cells release water and minerals for transport to the xylem?

• Into the cytoplasm

• Into the cell walls

• Into the soil

• Into the phloem

What is the final destination of water and minerals after they are transported across the cortex?

• Phloem

• Root hair cells

• Root xylem

• Epidermis
