how is water observed by root. explain with an experiment with diagram please​

Answer 1

Root hairs grow out into the space between the soil particles and that the hairs are surrounded by moisture. The soil water is an extremely dilute solution of salts, more dilute than that of the cell sap in the root hair, therefore water will pass into the vacuole of the root hair by osmosis.
