Which of the following are important components of long-distance transport process in xylem?
I. the cohesion of water molecules
II. a negative water potential
III. the active transport of solutes
IV. bulk flow from source to sink

Question

Quizplus · Accepted Answer

I. The cohesion of water molecules is crucial for the movement of water through the xylem in plants, as it allows for the continuous column of water to be pulled up from the roots to the leaves. II. A negative water potential gradient is necessary for the movement of water from the soil into the plant roots and then upwards through the xylem. III. Active transport of solutes is more relevant to the phloem and the movement of nutrients, not the xylem. IV. Bulk flow from source to sink describes the movement of sugars in the phloem, not water in the xylem.
