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 plant is able to take in as many important mineral ions as possible e.g. nitrates.

WebActive transport in the root hairs of plants allows plants to absorb mineral ions, which are necessary for healthy growth, even though the concentration of minerals is usually lower in the soil than in the root hair. Active transport Active transport is the net movement of particles against a concentration gradient. Energy is therefore required.
