The sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
<h3>What is diffusion?</h3>
Diffusion is the process by which substances move from region of high concentration to regions of low concentration.
Based on the chart, sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
This is because the ions are at higher concentration in the pond water.
During the process, the ions move through ion channels in and out of the plant cell from the pond water.
