Auxin transport within a plant is said to be _______ and it is dependent on the action of _______ pumps.

Question

Quizplus · Accepted Answer

Auxin transport within a plant is polar, meaning it occurs in a specific direction, from the shoot apical meristem towards the root. This transport is dependent on the action of proton pumps, which create an electrochemical gradient that allows for the movement of the charged auxin molecules. Nonpolar transport, such as diffusion, would not be able to achieve the directional movement of auxin necessary for proper plant growth and development. Potassium and sodium pumps are not involved in auxin transport. Bidirectional transport of auxin does occur, but it is not the primary mode of transport within the plant.
