As always, water moves by osmosis to where the water potential is lower. In this way, as water is always being absorbed by the root hairs, water will always move towards the centre of the root.

For which process is a root hair cell adapted? Filo

Web- (root hair cells) cannot take up mineral ions (by active transport) - so (plant) cannot make , proteins / amino acids / DNA / chlorophyll etc - cannot generate water potential gradient (into roots) / water potential (in root hair cells) is too high - water can't be absorbed (∴ cells can't remain turgid) - less / no , photosynthesis WebTherefore, the purpose of root hair cells it to provide a large surface area for the movement of water to occur. Minerals are also absorbed through the root hair cells by active transport, as they need to be pumped against the concentration gradient.
