WebRoot hair cells have a very large surface area due to them being very long and having hair like projections. This allows more active transport of mineral ions to take place so the … WebIf a red blood cell is placed in water, water enters the cell by osmosis. Because the membrane is quite weak the cell will burst as the volume and therefore the pressure in the cell. Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis.
