Textbook Question
Chapter 36, Problem 18TYK
Which of the following mechanisms explains the movement of sucrose from source to sink?
- a. osmotic movement of water into the sucrose-loaded sieve-tube elements, creating a higher pressure in the source than in the sink
- b. tension created by pressure differences in the source and the sink
- c. active transport of sucrose through the sieve-tube cells driven by proton pumps
- d. the hydrolysis of starch to sucrose in mesophyll cells, which raises their water potential and drives the bulk flow of sap to the sink
