Apoplast pathway

Question 1

Most water travels via the … pathway

Answer 1

Most water travels via the apoplast pathway

Question 2

what is the apoplast pathway

Answer 2

Most water travels via the apoplast pathway (when transpiration rates are high), which is the series of spaces running through the cellulose cell walls, dead cells, and the hollow tubes of the xylem

Question 3

what process does water move down the apoplast pathway

Answer 3

The water moves by diffusion (as it is not crossing a partially permeable membrane)

Question 4

The water moves from what to what or what spaces

Answer 4

The water can move from cell wall to cell wall directly or through the spaces between cells

Question 5

is water moving faster in the apoplast or symplast

Answer 5

water moves more rapid in apoplastrapid than symplast

Question 6

When the water reaches the endodermis the presence of a thick, waterproof, waxy band of suberin within the cell wall blocks the

Answer 6

pathway

Question 7

Casparian strip is what

and what does it act as

Answer 7

When the water reaches the endodermis the presence of a thick, waterproof, waxy band of suberin within the cell wall blocks the apoplast pathway

This band is called the Casparian strip and forms an impassable barrier for the water

Question 8

When the water and dissolved minerals reach the Casparian strip they must take the

Answer 8

symplast pathway.
