Biology 3.1.3 Movement of water into and across roots

Explain how water enters the plant and spreads throughout the roots

Does soil have a high or low water potential? Why?

What are the three pathways in which water moves across the roots?

Does the apoplast pathway pass though the: Cytoplasm, cytoplasm and vacuoles, or the cell wall?

Does the symplast pathway pass though the: Cytoplasm, cytoplasm and vacuoles, or the cell wall?

Does the vacuolar pathway pass though the: Cytoplasm, cytoplasm and vacuoles, or the cell wall?

The cell wall must be _______ to allow for movement along the apoplast pathway

Is there a lot or little resistance in the apoplast pathway?

Where does the apoplast pathway stop?

What connects cells?

With the symplast pathway, water flows through the ___________

What process allows water to move along the symplast pathway?

What is the casperian strip?

What is the waxy substance that makes up the casperian strip?

What is the function of the casperian strip?

How and why does water move into the xylem?

Explain how sucrose is loaded into the phloem and how this forces movement of substances down the phloem? (**)
