Q

46
Q

Explain the mechanism of translocation using the numbers on the diagram

A
  1. sugars made in cells enter the seive tube by active transport
  2. water moves from the adjacent xylem vessels by osmosis because the sugar concentration is high in the phloem
  3. turgor pressure increases due to water entering
  4. tugor pressure pushes the solution through the seive plates
  5. sugars move from the seive tubes to into the cells of the sugar sink by active transport.
  6. water is drawn out of the seive tube into the xylem vessels by suction created by the transpiration stream
  7. turgor pressure decreased due to water leaving the seive tubes. the difference in pressure between 3 and 7 creates a pressure gradient which keeps the sugars moving in solution.

79
Q

Label the nephron and state what happens at each numbered region

A
