Question

based on the figure below, which of these experimental treatments would increase the rate of sucrose transport into a plant cell? decreasing cytoplasmic ph decreasing extracellular sucrose concentration decreasing extracellular ph adding a substance that makes the membrane more permeable to hydrogen ions

Explanation:

Sucrose transport uses H+/sucrose cotransport, driven by H+ gradient (higher extracellular H+). Decreasing extracellular pH increases [H+] outside, enhancing H+ diffusion and sucrose transport. Other options reduce the gradient or substrate availability.

Answer:

decreasing extracellular pH
