Arrange the given events that occur in phloem for removal of water from phloem to xylem:
I) Incoming sugars are actively transported out and removed as complex carbohydrates.
II) Increase of water potential.
III) Increase of hydrostatic pressure in sieve tubes.
IV) Transport of water into sieve tubes by osmosis.
MEDIUM
Choose the correct order of statements regarding the translocation of sucrose.
A) Loading of sugars into phloem setup a water potential gradient that facilitates mass movement in phloem.
B) Sucrose moves into companion cell and then to phloem sieve tube cell by active transport.
C) A hypertonic condition in phloem facilitating water from the xylem into phloem by osmosis.
D) All sink sugars are transported out of the phloem producing high water potential with returning of water to xylem.
E) With increase in hydrostatic pressure in phloem pressure flow begin and sap moves through phloem.
