(a) Foliar feeding
Explanation:
Potassium is accumulated by passive transport. Some solutes are pumped across membranes using active transport. The role of proton pumps in the transport process of plant cells is a specific application of chemiosmosis, a transmembrane proton gradient that links energy-releasing processes to energy-consuming ones like active transport.
