WebRoot hair cells. The root hair cells are where most water absorption happens. They are long and thin so they can penetrate between soil particles, and they have a large surface area for absorption of water through osmosis. Water passes from the soil water to the root hair cell’s cytoplasm by osmosis. This happens because the soil water has a ...
